AMMP-6650

­AMMP-6650 DC – 30 GHz Variable Attenuator Data Sheet Description The AMMP-6650 is a voltage controlled variable attenuator 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.
