Description
M/A-COM’s AT-108 is a GaAs, MESFET MMIC voltage
variable absorptive attenuator in a low cost SOIC-8 lead surface
mount plastic package. The AT-108 is ideally suited for use
where linear attenuation fine tuning and very low power
consumption are required. Typical applications include radio,
cellular, GPS equipment and automatic gain/level control
circuits.
The AT-108 is fabricated with a monolithic GaAs MMIC using
a mature 1-micron process.
