Metamorphic high electron mobility transistor (mHEMT) technologies with 100, 50, and 35 nm gate lengths have been developed at Fraunhofer IAF for operation in the millimeter-wave frequency range up to 600 GHz. Based on these technologies, a variety of multifunctional millimeter-wave and submillimeter-wave monolithic integrated circuits (MMICs and S-MMICs) has been realized. To demonstrate the potential of these technologies, this paper presents some examples of S-MMICs developed for use in next generation systems for safety and security applications: a 460 GHz amplifier and a 300 GHz heterodyne receiver. Furthermore, a complete 94 GHz imaging system for materials testing and concealed object detection is presented.
