MMIC Vector Topology Enabling Multi RF Functionalities for 5G and Beyond

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