HFA3761 Datasheet | Intersil

Data Sheet July 1999 File Number 400MHz AGC and Quadrature IF Demodulator The HFA3761 is a highly integrated baseband converter for quadrature demodulation applications. The HFA3761 400MHz AGC and quadrature IF demodulator is one of the seven chips in the PRISM® full duplex chip set (see Typical Application Diagram). It Features all the necessary blocks for baseband demodulation of I and Q signals. It has a two stage integrated AGC IF amplifier with 82dB of voltage gain and 76dB of gain control range. Baseband antialiasing and shaping filters are integrated in the design. Four filter bandwidths are programmable via a two bit digital control interface. In addition,...
