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 

0.5 micron 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.
