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.
