Description
M/A-COM’s MAALSS0045 is a high dynamic range,
GaAs MMIC, low noise amplifier in a lead-free 3 mm
12-lead PQFN package.
It employs external
matching to obtain optimum noise figure and
intercept performance.
The MAALSS0045 is
operated with a supply voltage of +5V.
The MAALSS0045 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 MAALSS0045 is fabricated using a low-cost
0.5-micron gate E-D SAGFET GaAs process. This
process features full passivation for increased
reliability. The MAALSS0045 is 100% RF tested to
ensure performance specification compliance.
