AMMC-6650
DC–40 GHz Variable Attenuator
Data Sheet
Description
The AMMC-6650 is a voltage controlled variable attenua-
tor designed to operate from DC-40 GHz. It is fabricated
using Avago Technologies enhancement mode pHEMT
MMIC process with backside ground vias, and gate lengths
of approximately 0.25um. The distributed topology of the
AMMC-6650 facilitates broadband operation by absorbing
parasitic effects of its series and shunt FETs. An on-chip DC
reference circuit may be used to maintain optimum VSWR
for any attenuation setting or to provide more linear
attenuation versus voltage response.
