Product Descriptions
RFMD’s RFSA2033 is a fully monolithic analog voltage controlled attenuator (VCA) featuring exceptional linearity over a typical temperature-compensated 25dB gain control range and low insertion loss of 1.0dB typical. 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 polarity of the control voltage versus gain is selectable. The RFSA2033 draws a very low 2.5mA current. This attenuator is
matched to 50? over its rated control range and frequency with no external matching components require. 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 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 in area and reduces the DC power over conventional PIN diode approaches.
