Abstract: In-band full-duplex is a promising air interface technique to tackle several of the key challenges of next generation (5G) mobile networks. Simultaneous transmission and reception in the same frequency band increases the throughput and spectral efficiency, and reduces the air interface delay. Its implementation in 5G systems, however, restrains the full-duplex transceiver design requirements. Two analog integrated circuit solutions are presented and evaluated in the frame of 5G applications. The first design is a self-interference cancelling front-end implemented in 65nm CMOS, and the second design is an electrical-balance duplexer implemented in 0.18µm RF SOI CMOS. Both designs are attractive in the context of 5G they allow dense integration, are configurable to support alternative and legacy standards, are compatible with conventional antenna(s), and they provide an attractive full-duplex performance for wireless communications.
