Product Description
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...
