Description
M/A-COM's AT-108 is a GaAs MESFET MMIC
voltage variable absorptive attenuator in a low cost
SOIC-8 surface mount plastic package. The AT-108
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-108 is fabricated with a monolithic GaAs
MMIC using a mature 1-micron process.
The
process features full chip passivation for increased
performance and reliability.
