Description

4 X 1 2 °

M/A-COM’s AT-118 is a linear GaAs MMIC voltage variable

absorptive attenuator in a low cost MSOP-8 surface mount

plastic package. The AT-118 is ideally suited for applications

where linear attenuation and fine tuning are required.

Typical applications include radio, cellular, GPS equipment and

automatic gain/level control circuits.

1. Dimensions are in inches.

The AT-118 is fabricated with a mature 1 micron gate length

GaAs MESFET process. The process features full chip

passivation for increased performance and reliability.
