Description
M/A-COM’s AM50-0012 is a high dynamic range, GaAs
MMIC, low noise amplifier in a low-cost small footprint
3mm FQFP-N 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 0.5-micron
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.
Electrical Specifications: TA = 25°C, Z0 = 50 Ohm, F = 2000 MHz, PIN = -30 dBm
