Description

M/A-COM’s AM50-0011 is a high dynamic range, GaAs
MMIC, low noise amplifier in a low-cost SOT-26 package.
It employs external matching to obtain optimum noise
figure and intercept performance. The AM50-0011 may be
operated with supply voltages of +5 V.

The AM50-0011 is ideally suited for use where low noise
figure, high gain, and high dynamic range are required.
Typical applications included receiver front ends in AMPS,
GSM and ETACS base stations. It may also be used as an
IF amplifier in certain other communication systems.

M/A-COM fabricates the AM50-0011 using a low-cost 0.5­micron gate E-D SAGFET GaAs process that features full
passivation for reliability and performance. M/A-COM
fully tests all assembled GaAs IC’s for RF and DC
performance against guaranteed specifications using
automated RF IC handling and test equipment before
shipping to customers.
