oral virtual. International audience. This paper presents a multi-functional topology of a monolithic microwave monolithic integrated circuit (MMIC) capable of performing both wireless communications and geolocation devices. The architecture of this MMIC allows several RF functionalities such as conventional frequency heterodyning for high-speed IQ modulation. In addition, the device can be configured in quadratic sensing mode to achieve optimal power added efficiency (PAE). The topology developed in the 65 nm FDSOI CMOS technology enables wide frequency band of operation and combines vector accuracy for high data rates and phase state determination. The results presented concern QPSK and 16QAM modulation schemes at data rates up to 2 Gbps as well as essential geolocation measurements such as Time Difference of Arrival (TDoA) and Angle of Arrival (AoA). The expected performance in terms of location accuracy is also presented.
