3V to 5V, 5mA • High Dynamic Range • DC Decoupled RF Input and Output • No External RF Tuning Elements Necessary • Low Cost SOIC 8 Lead Plastic Package The Intersil HFA3424 PRISM™ is a high performance low noise amplifier in a low cost SOIC 8 lead surface mount plastic package.
The HFA3424 employs a fully monolithic design which eliminates the need for external tuning networks.
It can be biased using 3V or 5V supplies and has an option for biasing at higher currents for increased dynamic range.
The HFA3424 is ideally suited for use where low noise figure, high gain, high dynamic range and low power consumption required.
Typical applications include receiver front ends in the Wireless Local Area Network (WLAN) and wireless data collection markets in the 2.
4GHz Industrial, Scientific and Medical (ISM) band, as well as standard gain blocks, buffer amps, driver amps and IF amps in both fixed and portable systems.
Applications • Systems Targeting IEEE 802.
