Description
M/A-COM’s AT-110-2 is a GaAs MMIC voltage
variable absorptive attenuator in a low-cost SOIC 8-
lead surface mount plastic package. The AT-110-2
has a faster switching speed than the AT-108 or
AT-109. The AT-110-2 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-110-2 is fabricated with a monolithic GaAs
MMIC using a mature 1-micron process. The
process features full chip passivation for increased
performance and reliability.
