RF2368
DCS/PCS 2.7V LOW NOISE AMPLIFIER
Typical Applications
• DCS Handsets
• PCS Handsets
• General Purpose Amplification
• Commercial and Consumer Systems
Product Description
The RF2368 is a DCS/PCS low noise amplifier with
bypass switch designed for use as a front-end for
DCS1800/PCS1900 applications. The LNA is a two-stage
amplifier with bypass switch. This amplifier has low noise
figure and high linearity in both high gain and bypass/low
gain mode.
