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

Applications
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.
1. VCC = +3.3 VDC @ 50 µA max.
2. VCTL = 0 VDC to +3.3 VDC @ 50 µA max.
3. External DC blocking capacitors are required on all RF
ports.
