Abstract : This paper presents a vector topology of a monolithic microwave integrated circuit (MMIC) capable of performing several radiofrequency (RF) functionalities essential for future wireless communications and geolocation in the millimeter frequency band. The proposed circuit can address several usage modes such as conventional frequency heterodyning for high-speed IQ modulation and demodulation. In addition, the device can be configured in six-port quadratic detection mode to achieve optimum power added efficiency (PAE). The topology developed in 65 nm FDSOI CMOS technology achieves broadband V-band frequency operation and combines vector precision for both high data rates and phase state determination. The results presented concern QPSK modulation schemes at data rates up to 4 Gbps as well as essential geolocation metrics such as time domain of arrival (TDoA) and angle of arrival (AoA). The combination of vector accuracy/PAE together with wide linear operating range makes this topology a viable candidate for next generation radio frequency systems.
