Description
M/A-COM’s MAALSS0025 is a high dynamic
range, low noise GaAs MMIC amplifier in a low
cost, surface mount package. It employs external
input matching to obtain optimum noise figure
performance and operating frequency flexibility.
The MAALSS0025 also features flexible biasing to
control the current consumption vs. dynamic range
trade-off. The MAALSS0025 can operate from any
supply voltage in the 3 V to 8 V range. Its current
can be controlled over a range of 20 mA to 80 mA
with an external resistor.
The MAALSS0025 is ideally suited for use where
low noise figure, high gain, high dynamic range,
and low power consumption are required. Typical
applications include receiver front ends in
CDMA450 base stations. It is also useful as a gain
block, buffer, driver, and IF amplifier in both fixed
and portable cellular and 450 MHz ISM
systems.
The MAALSS0025 is fabricated using a low-cost
0.5-micron gate length GaAs process. The
process features full passivation for increased
performance reliability.
