Quick Detail:

400MHz Quadrature Modulator and AGC

Description:

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 ?lters are integrated in the design. Four ?lter bandwidths are programmable via a two bit digital control interface. In addition, these ?lters are continuously tunable over a ±20% frequency range via one external resistor. The modulator channel receives digital or analog I and Q data for processing. To achieve broadband operation, the Local Oscillator frequency input is required to be twice the desired frequency of modulation. A selectable buffered divide by 2LO output and a stable reference voltage are provided for convenience of the user.
