Description

M/A-COM’s AM50-0004 is a high dynamic range,

GaAs MMIC, low noise amplifier in a low cost, SOIC

8-lead, surface mount, plastic package. It employs

external input matching to obtain optimum noise

figure

performance

and

operating

frequency

flexibility.

The AM50-0004 also features flexible

biasing to control the current consumption vs.

dynamic range trade-off.

The AM50-0004 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 AM50-0004 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 AM50-0004 is fabricated using a low-cost 0.5-

micron gate length GaAs process.

The process

features full passivation for increased performance

and reliability. The AM50-0004 is 100% RF tested

to ensure performance specification compliance.
