­AMMP-6650
DC – 30 GHz Variable Attenuator
Data Sheet
Description
The AMMP-6650 is a voltage controlled variable attenua-
tor in a surface mount package, designed to operate from
DC to 30 GHz. It is fabricated using Avago Technologies
enhancement mode pHEMT MMIC process and requires
only positive voltage control. The distributed topology
of the AMMP-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.
