In-band full-duplex (IBFD) technology is promised to deliver us from the scarcity of spectral resources as well as create novel multifunction wireless systems [1] . This concept was initially investigated in the 1960s for continuous-wave radar applic

In-band full-duplex (IBFD) technology can enable unique system capabilities and network architectures by allowing devices to transmit and receive on the same frequency at the same time. While previously considered impossible, this ability can now be

In this paper we present a fully CMOS-compatible fabrication process for GaN-on-Si monolithic microwave integrated circuits (MMICs) on 200-mm-diameter wafers. This process also enables wafer-level 3D integration of GaN MMICs with Si CMOS circuits to
