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 HFA3424 2.4GHz - 2.5GHz low noise amplifier is an optional chip that can be added to the five chips in the PRISM™ chip set. The HFA3424 offers increased sensitivity for systems targeting 802.11 specifications. (See Figure 1, the Typical Application Diagram.)
