The HMC677 devices are multifunction BiCMOS control interface integrated circuits (ICs), which are ideal for driving the gates of field effect transistor (FET) and pseudomorphic high electron mobility transistor (pHEMT) based monolithic microwave integrated circuit (MMIC) control devices. This unique IC can be used to simplify the control of microwave and millimeterwave transmit/receive modules, military subsystems, and multithrow/multiport test and measurement equipment. The HMC677 devices accept serial or parallel data and can drive up to six complementary sets of outputs.

The HMC677 devices also provide additional functionality such as a power-up state selection, adjustable output voltage levels, and a latched parallel control mode which allows multiple control devices to share a common data bus. The HMC677 devices are ideal for controlling digital phase shifters, digital attenuators, digital variable gain amplifiers, and switching matrices embedded in complex microwave and millimeterwave assemblies.
