It incor- Compensation porates 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 Class 1C ESD (1000V) linear in dB control voltage characteristic. This voltage controlled attenuator is controlled by a Complete Solution in a Small single positive control voltage with on-chip DC conditioning circuitry. The slope of the control 3mm x 3mm, QFN Package voltage versus gain is selectable. The RFSA2023 draws a very low 1mA current and is packaged in a small 3mm x 3mm QFN. This attenuator is matched to 50 over its rated control range and 5V Part Available RFSA2013 frequency with no external matching components required. Typical VCA s in this performance category have poor inherent attenuation versus temperature and poor nonlinear attenuation versus control voltage characteristics. To correct these shortcomings, other VCA s require exten- Applications sive 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 Cellular, 3G Infrastructure package that reduces the footprint by 20X in area and reduces the DC power by 10X over con- WiBro, WiMax, LTE ventional P diode approaches.
