Description
M/A-COM鈥檚 AT-113 is a GaAs MMIC voltage variable
absorptive attenuator in a low cost SOIC 8-lead surface mount
plastic package. The AT-113 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-113 is fabricated with a monolithic GaAs MMIC using
a mature 1-micron process. The process features full chip
passivation for increased performance and reliability.
