Description
M/A-COM’s AM50-0012 is a high dynamic range,
GaAs MMIC, low noise amplifier in a low-cost small
footprint 3 mm 12-lead PQFN package. It employs
external matching to obtain optimum noise figure
and intercept performance. The AM50-0012 is
operated with a supply voltage of +5V.
The AM50-0012 is ideally suited for use where low
noise figure, high gain, and high dynamic range are
required. Typical applications included receiver
front ends in TDMA, CDMA, and DCS base stations.
It may also be used as an IF amplifier in certain
other communication systems.
The AM50-0012 is fabricated using a low-cost 0.5micron gate E-D SAGFET GaAs process. This
process features full passivation for increased
reliability. The AM50-0012 is 100% RF tested to
ensure performance specification compliance.
