Integrated Rx/Tx MMICs with in-phase and quadrature phase (IQ) data inputs were designed by the University of Stuttgart and manufactured on the Fraunhofer IAF's 35 nm mHEMT technology. The typical performance of a Tx MMIC is 1 mW measured output power and an IQ-channel conversion gain of 5 dB. For validation of the system concepts, Rx/Tx modules were developed.
