Product Summary

The AT-119TR-3000 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. The AT-119TR-3000 is ideally suited for applications that require fine tuning, linear attenuation with voltage, and very low power consumption. Typical applications for the AT-119TR-3000 include automatic gain control circuits in satellite radio receivers and other wireless receivers.
