It incorporates a Internal Temperature Compensation revolutionary new circuit architecture to solve a long standing industry problem: Low Distortion with -65dBc CSO, CTB high IP3, high attenuation range, low DC current, broad bandwidth, and and XMOD temperature-compensated linear in dB control voltage characteristic. This voltage Class 2 ESD (2000V HBM) controlled attenuator is controlled by a single positive control voltage with on chip Complete Solution in a Small 3mm x DC conditioning circuitry. The slope polarity of the control voltage versus gain is 3mm, QFN Package selectable. The RFSA2033 draws a very low 2.5mA current. This attenuator is Applications matched to 50 over its rated control range and frequency with no external matching components require. Typical VCAs in this performance category have Cellular, 3G Infrastructure poor inherent attenuation versus temperature and poor nonlinear attenuation WiBro, WiMax, LTE versus control voltage characteristics. To correct these shortcomings, other VCAs Microwave Radio require extensive off chip analog support circuitry that consume valuable PCB High-linearity Power Control area and additional DC power. This game changing product incorporates the Cable Modems complete solution in a small 3mm x 3mm QFN package that reduces the footprint CATV in area and reduces the DC power over conventional PIN diode approaches.
