Description
M/A-COM’s AT-250 is a GaAs MMIC voltage
variable absorptive attenuator in a low cost SOIC 8-
lead surface mount plastic package. The AT-250 is
ideally suited for use where attenuation fine tuning,
fast switching and very low power consumption are
required.
Typical applications include radio, cellular, GPS
equipment and other automatic gain/level control
circuits.
The AT-250 is fabricated with a monolithic GaAs
MMIC using a mature 1-micron process. The
process features full chip passivation for increased
performance and reliability.
