1.7GHz - 2.3GHz Low Noise Amplifier
The Intersil HFA3421 PRISM® is a high
performance low noise amplifier in a
low cost SOIC 8 lead surface mount
plastic package. The HFA3421 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 HFA3421 is ideally suited for use where low noise
figure, high gain, high dynamic range and low power
consumption are required. Typical applications include
receiver front ends in the Wireless Local Loop (WLL)
systems, as well as standard gain blocks, buffer amps, driver
amps and IF amps in both fixed and portable systems.
