Description
The HMMC-1002 is a monolithic, voltage variable, Ga As 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.
