AT-119 General Description
M/A-COM's AT-119 is a GaAs MMIC voltage variable absorptive attenuator in a low cost, SOT-25 five-lead,
surface mount plastic package. M/A-COM fabricates the AT-119 with a proven monolithic GaAs self-aligned gate
process that features full chip passivation for performance and reliability
AT-119 Features
Single Positive Voltage Control 0 to +2.25 Volts
>50 dB Attenuation Range at 2.1 GHz
Low DC Power Consumption
Low Cost SOT-25 Plastic Package
Tape and Reel Packaging Available
AT-119 Typical Application
The AT-119 is ideally suited for applications that require fine tuning, linear attenuation with voltage, and very low
power consumption.
Typical applications for the AT-119 include automatic gain control circuits in satellite radio receivers and other wireless receivers.
