HFA3763 Datasheet | Intersil

Data Sheet June 1999 File Number 400MHz Quadrature Modulator and AGC 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. In addition, these filters are continuously tunable over a ±20% frequency range via one external resistor. The modulator channel receives...
