Description

M/A-COM’s MAAMSS0045 is a high dynamic range,

GaAs MMIC, low noise amplifier in a lead-free

SOIC 8-lead, surface mount, plastic package.

It

employs external input matching to obtain optimum

noise figure performance and operating frequency

flexibility. The MAAMSS0045 also features flexible

biasing to control the current consumption vs.

dynamic range trade-off. The MAAMSS0045 can

operate from any positive supply voltage in the 3 V

to 8 V range. Its current can be controlled over a

range of 20 mA to 60 mA with an external resistor.

The MAAMSS0045 is ideally suited for use where

low noise figure, high gain, high dynamic range, and

low power consumption are required.

Typical

applications included receiver front ends in PDC,

DCS-1800, DCS-1900 and other PCN/PCS base

stations. It is also useful as a gain block, buffer,

driver, and IF amplifier in both fixed or portable PDC

and PCN/PCS systems.

The MAAMSS0045 is fabricated using a low-cost 0.5

-micron gate length GaAs process. The process

features full passivation for increased performance

and reliability.

The MAAMSS0045 is 100% RF

tested

to

ensure
