HMMC-1002
DC–50 GHz Variable Attenuator
Data Sheet
Description
The HMMC-1002 is a monolithic, voltage variable,
GaAs IC attenuator that operates from DC to 50 GHz.
It is fabricated using MWTC’s MMICB process which
features an MBE epitaxial layer, backside ground vias,
and FET gate lengths of approximately 0.4 mm. The
variable resistive elements of the HMMC-1002 are two
750 mm wide series FETs and four 200 mm wide
shunt FETs. The distributed topology of the HMMC-
1002 minimizes the parasitic effects of its series and
shunt FETs, allowing the HMMC-1002 to exhibit a
wide dynamic range across its full bandwidth. An on-
chip DC reference circuit may be used to maintain
optimum VSWR for any attenuation setting or to
improve the attenuation versus voltage linearity of
the attenuator circuit.
