AMMC-6640 Overview
The AMMC-6640 MMIC is a monolithic, voltage variable, GaAs IC attenuator that operates from DC-50 GHz. It is fabricated using Avago Technologies enhancement mode MMIC process with backside ground vias, and gate lengths of approximately 0.25um. The attenuator has a distributed topology and it helps to absorb parasitic effects of its series and shunt FETs to make it broadband.
