recent years due to multiple benefits such as increased spectral efficiency and improved network latency [1-5]. Several challenges remain in the quest for high-performance integrated FD radios. Transmitter (TX) power handling remains an open problem, particularly in FD radios that integrate a shared-antenna interface. Recent integrated shared-antenna interfaces that exhibit high power handling exploit SOI CMOS technologies and occupy substantial area [6]. Secondly, FD operation must be achieved across antenna VSWR variations and a changing EM environment. Finally, FD operation must be extended to multiple-antenna systems, as beamforming and MIMO are an integral part of emerging wireless networks. While the feasibility of combining FD with
