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.
