CIRCUIT DESCRIPTION

1. OverviewThe NX-300(G) is a UHF portable transceiver designed

to operate in the frequency range of 450 to 520MHz (K,K3) or 400 to 470MHz (K2,K4). The unit consists of receiver, transmitter, phase-locked loop (PLL) frequency synthesizer, base band parts, power supply, and control circuits.

2. Frequency Confi gurationThe receiver is a double-conversion superheterodyne us-

ing the fi rst intermediate frequency (IF) of 58.05MHz and the second IF of 450kHz. Incoming signals from the antenna are mixed with the local signal from the PLL circuit to produce the fi rst IF of 58.05MHz. This is then mixed with the 57.6MHz second local oscillator output to produce the 450kHz second IF. The transmit signal frequency is generated by the PLL VCO, and modulated by the signal from the DSP. It is then amplifi ed and fed to the antenna.

3. Receiver System3-1. RF Circuit

An incoming RF signal from the antenna terminal is passed through the antenna switch (D606, D607, D709, D711) and then the bandpass fi lter (L721, L722). The band-pass fi lter is adjusted by a variable capacitor. The input volt-age to the variable capacitor is regulated by the voltage out-put from the D/A converter (IC703). The signal is amplifi ed by an RF amplifi er (Q705), and passed through the band-pass fi lter (L713, L714, L715). The resulting signal is applied to the fi rst mixer (Q703), where it is mixed with the fi rst local oscillator signal output from the frequency synthesizer to produce the fi rst IF (58.05MHz).

3-2. IF CircuitThe fi rst IF signal is passed through a four-pole mono-

lithic crystal fi lter (XF700) to reject adjacent channel signals. The fi ltered fi rst IF signal is amplifi ed by the fi rst IF amplifi er (Q701) and then applied to the lF system IC (IC701). The IF system IC provides a second mixer, AGC amplifi er, and RSSI (Received Signal Strength Indicator).

The second mixer mixes the first IF signal with the 57.6MHz of second local oscillator output and produces the second IF signal of 450kHz.

The second IF signal is passed through the ceramic fi lter (CF700) to reject the adjacent channel signal. The fi ltered second IF signal is amplifi ed by the AGC amplifi er.

The signal from the AGC amplifi er is input to the ASIC (IC108) through the ceramic fi lter (CF701) and operational amplifi er (IC700).

3-3. Audio Amplifi er CircuitAudio processing (high-pass filter, low-pass filter, de-

emphasized and so on) at FM mode and decoding at NXDN mode are processed by DSP. The audio signal from IC108 and IC102 goes through the amplifier (IC704). The signal then goes through a mute switch (IC707), amplifi er (IC713), electronic volume control (IC703), and AF amplifi er (IC408).

While busy, AMT becomes Low to turn IC707 on, and the signal is fed to the AF switch. While INAMT is High, the AF switch (IC409) selects the internal speaker, and the audio signal is fed to the internal audio power amplifi er (IC413), and output to the internal speaker. While EXAMT is High, the AF switch (IC409) selects the external speaker, and the au-dio signal is fed to the external audio power amplifi er (IC412), and output to the external speaker. The power supply for IC413 and IC412 is turned on while INAMT or EXAMT is High.

The speaker is switched by the logic of the speaker switching terminal SSW on the universal connector. When the SP-MIC is not attached, SSW becomes High. IC108 detects the logic of SSW and activates either INAMT or EX-AMT.

4. Transmitter System4-1. Audio Band Circuit

The signal from the internal microphone goes through the mute switch (Q5). When the SP-MIC is not attached, the microphone switching terminal (MSW) on the universal con-nector becomes High, and the mute switch (Q5) is turned on. When the SP-MIC is attached, MSW is connected to GND inside the SP-MIC. For this reason, Q5 is turned off, the internal microphone is muted, and only the input of the external microphone is supplied to the microphone ampli-fi er. The signal from the microphone goes through the mute switch (Q707), and is amplifi ed by IC716 (1/2) and limited by the AGC circuit which is composed of D703, D704, Q705 and Q706.

4-2. Base Band CircuitThe audio signal output from the base band circuit is con-

verted to digital data with a sampling frequency of 48kHz. This digital data is sent to the DSP (IC102), and voice sig-nals of 300Hz or lower and frequencies of 3kHz or higher are cut off and an audio range of 300Hz to 3kHz is extracted. The audio signal is then pre-emphasized in FM mode and synthesized with the signals, such as QT and DQT, as re-quired, and is then output from IC108. In Digital mode, the audio signal is converted to the 4-Level FSK base band sig-nal and output from IC108. The DTMF and MSK base band signals are also generated by the DSP and output by IC108.

LPF (IC705) works as a smoothing fi lter. The DAC (IC703) assigns the base band signal to the VCO and VCTCXO (X500). At this time, the level output according to the trans-mit carrier is fine-adjusted according to each modulation method.

4-3. VOXIC716 (2/2) amplifi es the audio signal captured in the mi-

crophone. The signal is then converted into the DC voltage, rectifi ed by D706. The DC voltage activates the ASIC (IC108), and the VOX starts.

4-4. Drive and Final Amplifi erThe signal from the T/R switch (D601 is on) is amplifi ed

by the drive amplifi er (Q601,Q602 and Q603) to 25~27dBm. The output of the drive amplifi er is amplifi ed by the RF pow-er amplifi er (Q606) to 5.0W (1W when the power is low). The RF power amplifi er is MOS FET. The output of the RF power amplifier is then passed through the harmonic filter (LPF) and antenna switch (D606, D607 are on) and applied to the antenna terminal.

4-5. APC CircuitThe APC circuit always monitors the current flowing

through the RF power amplifi er (Q606) and keeps a constant current. The voltage drop at R642, R645 and R647 is caused by the current fl owing through the RF power amplifi er and this voltage is applied to the differential amplifi er (IC600 1/2). IC600 (2/2) compares the output voltage of IC600 (1/2) with the reference voltage from IC108, and the output of IC600 (2/2) controls the VGG of Q602, Q603 and Q606 to make the both voltages the same. The change of power high/low is carried out by the change of the reference voltage. Q607, Q608 and Q610 are turned on and Q604 and Q605 are turned off in transmit and the APC circuit is active.

5. PLL Frequency Synthesizer5-1. VCTCXO (X500)

VCTCXO (X500) generates a reference frequency of 19.2MHz for the PLL frequency synthesizer. This reference frequency is applied to pin 9 of the PLL IC (IC502) and con-nected to the IF circuit as a 2nd local signal through the Tripler (Q700). The VCTCXO oscillation frequency is deter-mined by the DC voltage of the VC terminal. The VC voltage is fi xed to 1.65V by R500 and R501, and supplied to the VC terminal through IC501. The modulation signal is also fed to the VC terminal through IC501.

The frequency adjustment is achieved by switching the ratio of the dividing frequency that is not adjusted by the DC voltage impressed to the VC. The resolution of the adjusting frequency is approximately 4Hz.

5-2. VCOThere is a RX VCO and a TX VCO.The TX VCO (Q509) generates a transmit carrier and the

RX VCO (Q508) generates a 1st local signal. For the VCO oscillation frequency, the transmit carrier is 450 to 520MHz (K,K3) or 400 to 470MHz (K2,K4) and the 1st local signal is 391.95 to 461.95MHz (K,K3) or 341.95 to 411.95MHz (K2,K4).

The VCO oscillation frequency is determined by one sys-tem of operation switching terminal “T/R” and two systems of voltage control terminals “CV” and “ASSIST”.

The operation switching terminal, “T/R”, is controlled by the control line (/T_R) output from the ASIC (IC108). When the /T_R logic is low, the VCO outputs the transmit carrier and when it is high, it outputs a 1st local receive signal.

The voltage control terminals, “CV” and “ASSIST”, are controlled by the PLL IC (IC502) and ASIC (IC108) and the output frequency changes continuously according to the applied voltage. For the modulation input terminal, “VCO_MOD”, the output frequency changes according to the ap-plied voltage. This is used to modulate the VCO output. “VCO_MOD” works only when “/T_R” is low.

NX-300(G)

5-3. PLL IC (IC502)The PLL IC compares the differences in phases of the

VCO oscillation frequency and the VCTCXO reference fre-quency, returns the difference to the VCO CV terminal and realizes the “Phase Locked Loop” for the return control. This allows the VCO oscillation frequency to accurately match (lock) the desired frequency.

When the frequency is controlled by the PLL, the fre-quency convergence time increases as the frequency differ-ence increases when the set frequency is changed. To sup-plement this, the ASIC is used before control by the PLL IC to bring the VCO oscillation frequency close to the desired frequency. As a result, the VCO CV voltage does not change and is always stable at approximately 2.5V.

The desired frequency is set for the PLL IC by the ASIC (IC108) through the 3-line “SDO1”, “SCK1”, “/PCS_RF” se-rial bus. Whether the PLL IC is locked or not is monitored by the ASIC through the “PLD” signal line. If the VCO is not the desired frequency (unlock), the “PLD” logic is low.

5-4. Local Switch (D600, D601)The connection destination of the signal output from the

buffer amplifier (Q600) is changed with the diode switch (D601) that is controlled by the transmission power supply, 50T, and the diode switch (D600) that is controlled by the receive power supply, 50R. If the 50T logic is high, it is con-nected to a send-side pre-drive (Q601). If the 50T logic is low, it is connected to a receive-side mixer (Q703).

6. Control CircuitThe control circuit consists of the ASIC (IC108) and its

peripheral circuits. IC108 mainly performs the following;1) Switching between transmission and reception by PTT

signal input.2) Reading system, zone, frequency, and program data from

the memory circuit.3) Sending frequency program data to the PLL.4) Controlling squelch on/off by the DC voltage from the

squelch circuit.5) Controlling the audio mute circuit by decode data input.

6-1. ASICThe ASIC (IC108) is a 32-bit RISC processor, equipped

with peripheral function and ADC/DAC.This ASIC operates at 18.432MHz clock and 3.3V /1.5V

DC. It controls the fl ash memory, SRAM, DSP, the receive circuit, the transmitter circuit, the control circuit, and the dis-play circuit and transfers data to or from an external device.

6-2. Memory CircuitThe memory circuit consists of the ASIC (IC108) and the

SRAM(IC103) and fl ash memory (IC101). The fl ash memory has capacity of 32M-bit that contains the transceiver control program for the ASIC and stores the data. It also stores the data for transceiver channels and operating parameter that are written by the FPU. This program can be easily written from external devices. The SRAM has capacity of 1M-bit that contains work area and data area.

■ Flash memoryNote: The fl ash memory stores the data that is written by the FPU (KPG-111D), tuning data (Deviation, Squelch, etc.) ,and fi rmware program (User mode, Test mode, Tuning mode, etc.). This data must be rewritten when replacing the fl ash memory.

■ SRAM (Static memory)Note: The SRAM has temporary data area and work area.When the power supply is off, it is backed up by an internal secondary lithium battery. Therefore, the saved data is not lost.

■ Real-time clockThe clock function is based on real-time clock IC (IC106).

When the power supply is off, it is backed up by an internal secondary lithium battery.

6-3. LCDThe LCD is controlled using the bus lines on the connec-

tor (CN1) of the Control unit (X53-426). It corrects the LCD contrast voltage using IC1.

6-4. Key Detection CircuitKeys are detected using the key scan circuit in IC108.

The /KEYI* signals that are normally pulled down go high when any key is pressed.

6-5. Low Battery WarningThe battery voltage is divided using R444 and R445 and

is detected by the ASIC (IC108). When the battery voltage falls below the voltage set by the Low battery warning ad-justment, the red LED blinks to notify the operator that it is time to replace the battery. If the battery voltage falls even more (approx. 5.8V), a beep sounds and transmission stops.

Low battery warning Battery condition

The red LED blinks during transmission.

The battery voltage is low but the transceiver is still usable.

The red LED blinks and the warning tone beeps while the PTT switch is pressed.

The battery voltage is low and the transceiver is not usable to make calls.

6-6. DSPThe DSP circuit consists of a DSP (IC102) and process-

es the base band signal. The DSP operates on an external clock of 18.432MHz (the same as the IC108), the I/O section operates at 3.3V and the core section operates at 1.5V. The DSP carries out the following processes: • 4 Level FSK processing • Analog FM pre-emphasis/de-emphasis • Vocoder processing between audio codec and modula-

tion/demodulation • CAI processing, such as error correction encoding • QT/DQT encoding/decoding • LTR encoding/decoding • DTMF encoding/decoding • MSK encoding/decoding • 2-tone encoding/decoding • Compressor/expander processing • Voice scrambler processing • Transmit/receive audio fi ltering processing • Microphone amplifi er AGC processing • Audio mute processing • Modulation level processing

7. Power Supply CircuitThe battery voltage (+B) is provided from the battery ter-

minal on the TX-RX unit (X57). The battery voltage passes through the 2.5A fuse (F900), and goes to the RF fi nal am-plifi er, AVR ICs (IC902, IC903), and Control unit (X53).

In the control unit, +B is connected to the DC/DC (IC407), AVR ICs (IC411, IC708, IC416), and voltage detector IC (IC414). The voltage detector watches the battery voltage. If the battery voltage is 5.6V or higher, the detector outputs High. While the output of IC414 is High, IC416 and Q409 provide 3.1V (31BU) to the backup-section.

When the VOL SW is turned on, SB1 becomes high (bat-tery voltage). The DC/DC (IC407) operates if both SB1 and the output of the detector are high. IC407 outputs 3.8V and it activates IC404 (33M), IC717 (15M), and IC406 (33A). As a result, the ASIC and DSP operate.

The SBC signal becomes High after the ASIC operates, IC708 (5A), Q403 on the Control unit (SB2) and Q901 on the TX-RX unit (SB3) are turned on. IC901 and IC903 operate by turning on these AVR ICs and FET switches.

The 5UC signal becomes High when an option is in-stalled on the universal connector. Then IC411 (50U) oper-ates.

When the /SAVE signal becomes High, IC902 (50C) operates. The output of IC902 is connected to three FET switches (Q902, Q903, Q905). When the SBC signal be-comes High, IC903 (33C) operates. The FET switches are controlled by the CPU. Q905 (50T) is turned on in transmit mode. Q902 (50R) and Q903 (50IF) are turned on in receive mode.

When the VOL SW is turned off the /PSW signal be-comes Low. After detecting the /PSW signal, the ASIC changes SBC signal to Low. Then the power supplies except IC416 (31BU) stop.

CIRCUIT DESCRIPTION

8. Signaling Circuit8-1. Encode (QT/DQT/LTR/DTMF/2-tone/MSK)

Each signaling data signal of QT, DQT, LTR, DTMF, 2-tone and MSK is generated by the DSP circuit, super-posed on a modulation signal and output from IC108. The modulation balance of the QT/DQT/LTR signal is adjusted by the D/A converter (IC703) and the resulting signal is routed to the modulation input of the VCO and VCXO (X500). Each deviation of the TX QT, DQT, LTR, DTMF, 2-tone and MSK tone is adjusted by changing the output level of IC108 and the resulting signal is routed to the VCO and VCXO. The RX DTMF tone is routed to the receive audio signal system, and is output from the speaker.

8-2. Decode (QT/DQT/LTR/DTMF/2-tone/MSK)The audio signal is removed from the FM detection signal

sent to the DSP circuit and the resulting signal is decoded.

9. Compander CircuitThe term “compander” means compressor and expander.

The compander reduces noise by utilizing a compressor and an expander. The transceiver contains a DSP (IC102) to perform this operation. The transceiver compander can be turned on or off using the FPU.

10. GPS CircuitThe GPS information function can be used by setting it

through the FPU. When the GPS information function is en-abled, the AVR (IC4/GPS) is enabled by the OPT5, and is supplied to the GPS circuit.

The GPS circuit block consists of a TX-RX unit and a GPS unit (X58). The circuit from an antenna to LNA is on a TX-RX unit. This output is connected to the GPS unit by the coaxial cable.

The GPS signal of 1575.42MHz received with the an-tenna (with GPS band) is passed by the HPF and BPF (L605/TX-RX) and is amplified by the LNA (IC881/TX-RX). The GPS signal is processed by the GPS IC (IC1/GPS) and in-put to the ASIC (IC108/CONT) through the UART port. The ASIC (IC108/CONT) processes the GPS data (NMEA) and sends the resulting information to the LCD.

The GPS IC operates in stand-alone. Operating voltage is 3.1V. When the transceiver power is off, the GPS IC will be backed up with the internal coin battery. When the battery pack is removed, the GPS IC will be backed up for about one day in a coin battery. But if the GPS IC has never had the position fi xed, it will not be backed up.

When the GPS function is enabled, the consumption cur-rent increases by about 70 mA.

TROUBLE SHOOTING

Fault Diagnosis of the BGA (Ball Grid Array) IC■ Overview A fl owchart for determining whether or not the transceiver can be powered on (the LCD does not function even if the power

switch is turned on) due to broken BGA parts.

■ BGA partsASIC (IC108), DSP (IC102), FLASH (IC101), SRAM (IC103)

When the BGA IC is problematic, please bring the printed circuit board (X53-4590-12 for 6-key, X53-4590-13 for 18-key) in for service. Various ESN/default adjustment values are written on the printed circuit board for service.

Additionally various ESN stickers are included. (Please refer to pages 39 and 40.) Button type lithium battery (W09-0971-05) does not belong to the printed circuit board for service. Please use the part which

has been attached to the printed circuit board. After the printed circuit board has been readjusted, please attach any ESN stickers to the chassis. When “ESN Validation” is used with NXDN Trunking, you must modify the ESN register.

ing, the NXDN ESN number changes when the circuit board is changed (the number is written on the circuit board); the NXDN Trunking System cannot be accessed. Use the KPG-110SM on the NXDN Trunking System side to reprogram the NXDN ESN number.

• When a new printed circuit board is used, the Kenwood ESN changes, as does the Transceiver Information dis-play of the KPG-111D/111DN, but this does not have any effect on the operation of the transceiver.

• If changing to the original Kenwood ESN and NXDN ESN, please contact our service center.

■ Preparations for checking/tuning the transceiverBefore attempting to check/tune the transceiver, connect

the unit to a suitable power supply.Whenever the transmitter is turned on, the unit must be

connected to a suitable dummy load (i.e. power meter).The speaker output connector must be terminated with a

8 dummy load and connected to an AC voltmeter and an audio distortion meter or a SINAD measurement meter at all times during checking/tuning.

Panel Test Mode■ Test mode operation features

This transceiver has a test mode. To enter test mode, press and hold the [ ] key while turning the transceiver power ON. Before the transceiver enters test mode, the frequency version information appears on the LCD mo-mentarily. Test mode can be inhibited by programming.

ADJUSTMENT

■ Antenna connector adapterThe antenna connector of this transceiver uses an SMA

terminal.Use an antenna connector adapter [SMA(f) – BNC(f) or

SMA(f) – N(f)] for adjustment. (The adapter is not provided as an option, so buy a commercially-available one.)

■ Nut wrenchIn order to turn the volume nut and the channel selector

nut, use a recommendation tool.KENWOOD part No.: W05-1123-00

■ Battery jig (W05-1370-00)Connect the power cable properly between the battery

jig installed in the transceiver and the power supply, and be sure output voltage and the power supply polarity prior to switching the power supply ON, otherwise over voltage and reverse connection may damage the transceiver, or the power supply or both.

+ Terminal (Red)

- Terminal (Black)

Note: • When using the battery jig, you must measure the volt-

age at the terminals of the battery jig. Otherwise, a slight voltage drop may occur within the power cable, between the power supply and the battery jig, especially while the transceiver transmits.

• The battery jig is detected as “Li-ion High Capacity Bat-tery”.

■ Universal connectorUse the interface cable (KPG-36A/36U) for PC tuning or

the lead wire with plug (E30-3287-28) and screw (N08-0535-08) for panel tuning. Connect the plug to the universal con-nector of the transceiver and tighten the screw.

The lead wire with plug (E30-3287-28) and screw (N08-0535-08) terminals are as follows. Numbers are universal connector terminal numbers.

Caution1. When connecting the plug to the universal connector of

the transceiver, a short circuit may occur. To prevent this, be sure to turn the transceiver POWER switch off.

2. Since the RX AF output is a BTL output, there is a DC component. Isolate this with a capacitor or transformer as shown in the fi gure.

3. Do not connect an instrument between red or black and GND.
