Radio complexity in the age of 5G

Sub-6GHz and 5G mmWave approaches

Connected Intelligence and its importance for 5G realization4

Closing thoughts5

We are well-versed in how sub-6 GHz FEMs have changed over time in response to higher CAT support…

3

Growth of bands added to complexity due to

other features like carrier aggregation, MIMO etc.

LTE Advanced

Max #bands >30Max #bands ~20

LTE3G

Max #bands ~10

2G

Max #bands 4

• Sub 6 GHz 5G bands will have 5,10, 20, 25, 30, 40, 50, 60, 80,100 MHz channel bandwidths

• Bands N1, 2, 5, 7, 8, 20, 28 (all FDD), F38, 51 (TDD), F71, 74 (FDD), and F76, 81-84 have channel BW of 20 MHz or less, like 4G

5G NR sub-6GHz frequency band specifications significantly increase frequency range and channel bandwidth

Band UL Frequency Range Max Channel BW

N41 (2.46-2.69 GHz)

N77 (3.30-4.20 GHz)

N78 (3.30-3.80 GHz)

N79 (4.40-5.00 GHz)

100 MHz (4%)

N50 (1.43-1.52 GHz) 80 MHz (5.6%)

N66 (1.71-1.78 GHz) 40 MHz (2.3%)

N3, N80 (1.71-1.78 GHz) 30 MHz (1.8%)

5G/mmWave phased arrays drive a paradigm shift in the approaches that can be taken…greater integration is needed

7

• Smallest # of components

• Lowest power dissipation

• Most sensitive to interconnect loss

• Complexity in phase shifting

• Large # of components

• High power dissipation (except for FDX)

• Simple to implement

• For large array where analog & digital beamforming are inefficient and complex
