The HFA3763 is a highly integrated baseband converter for quadrature modulation applications. The HFA3763 400MHz quadrature modulator and AGC 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 modulation of I and Q signals. An output AGC and Baseband shaping filters are integrated in the design. Four filter bandwidths are programmable via a two bit digital control interface.
