Description
M/A-COM’s 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.
