It incorporates a revolutionary new circuit architecture to solve a long standing industry problem: high IP3, high attenuation range, low DC current, broad bandwidth and temperature compensated linear in dB control voltage characteristic. This voltage controlled attenuator is controlled by a single positive control voltage with on-chip DC conditioning circuitry. The slope of the control voltage versus gain is selectable. The RFSA3013 draws a very low 1mA current and is packaged in a small 3mm x 3mm QFN. This attenuator is matched to 75 over its rated control range and frequency with no external matching components required. Typical VCAs in this performance category have poor inherent attenuation versus temperature and poor nonlinear attenuation versus control voltage characteristics. To correct these shortcomings, other VCAs require extensive off chip analog support circuitry that consume valuable PCB area and additional DC power. This game changing product incorporates the complete solution in a small 3mm x 3mm QFN package that reduces the footprint by 20X in area and reduces the DC power by 10X over conventional PIN diode approaches.
