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.
