RFSA2013VOLTAGE CONTROLLED ATTENUATOR
RFMD's RFSA2013 is a fully monolithic analog voltage controlled attenuator (VCA) featuringexceptional linearity over a typical temperature compensated 30dB gain control range. It incor-porates a revolutionary new circuit architecture to solve a long standing industry problem: highIP3, high attenuation range, low DC current, broad bandwidth and temperature compensatedlinear in dB control voltage characteristic. This voltage controlled attenuator is controlled by asingle positive control voltage with on chip DC conditioning circuitry. The slope of the controlvoltage versus gain is selectable. The RFSA2013 draws a very low 1mA current and is pack-aged in a small 3mm x 3mm QFN. This attenuator is matched to 50 over its rated controlrange and frequency with no external matching components required. Typical VCA's in this per-formance category have poor inherent attenuation versus temperature and poor nonlinearattenuation versus control voltage characteristics. To correct these shortcomings, other VCA'srequire extensive off chip analog support circuitry that consume valuable PCB area and addi-tional DC power. This game changing product incorporates the complete solution in a small3mm x 3mm QFN package that reduces the footprint by 20X in area and reduces the DC powerby 10X over conventional PIN diode approaches.

PCB Patterns
Thermal vias for center slug “C” should be incorporated into the PCB design. The number and size of thermal vias will depend on the application, the power dissipationand the electrical requirements. Example of the number and size of vias can be found on the RFMD evaluation board layout.
