Description
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.
The AT-118 is fabricated with a mature 1 micron gate length
GaAs MESFET process.
