400mhz Quadrature If Modulator/demodulator

The Intersil 2.4GHz PRISM chip set is a highly integrated five-chip solution for RF modems employing Direct Sequence Spread Spectrum (DSSS) signaling. The HFA3724 400MHz Quadrature IF Modulator Demodulator is one of the five chips in the PRISM chip set (see the Typical Application Diagram). The HFA3724 is a highly integrated baseband converter for quadrature modulation applications. It features all the necessary blocks for baseband modulation and demodulation of I and Q signals. It has a two stage integrated limiting IF Amplifier with 84db of gain with a built in Receive Signal Strength Indicator (RSSI). Baseband antialiasing and 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.
