HFA3763
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 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 2
LO output and a stable reference voltage are provided for
convenience of the user.
