Description
M/A-COM鈥檚 AT-110 is a linear GaAs MMIC voltage
variable absorptive attenuator in a low-cost SOIC
8-lead surface mount plastic package. The AT-110 has
a faster switching speed than the AT-108 or AT-109.
The AT-110 is ideally suited for use where linear
attenuation fine tuning and very low power com-
sumption are required. Typical applications include
radio,
cellular, GPS equipment and automatic gain/level
control circuits.
The AT-110 is fabricated with a monolithic GaAs
MMIC using a mature 1-micron process. The process
features full chip passivation for increased perfor-
mance and reliability.
