“…In fact, given the limited antenna isolation (in the order 20-30 dB [14]), diversity receiver linearity and reciprocal mixing with the receiver local oscillator phase noise are major issues [15]- [21]. TX leakage cancellation techniques, where a vector modulator connected to the transmitter or an auxiliary transmitter [22]- [26] injects a replica TX signal at the receiver input, have been proposed to relax the receiver requirements. The frequency separation between TX and RX can be exploited to improve the linearity of the receiver through filtering, e.g., embedding N-path filters in the receiver front-end [27]- [35], [57].…”

Antenna-coupling group delay limits the cancellation bandwidth of conventional self-interference cancellers (SICs), making it difficult to ensure isolation in both transmit (TX) and receive (RX) bands. Isolation over both bands is achieved in the dual-path receiver architecture proposed in this paper. The main path consists of a highly linear current-mode RX with a passive RF SIC. The auxiliary path implements a notch in the TX band followed by an adaptive digital equalizer whose output is used to suppress the TX noise leakage in the RX band. The main and auxiliary receiver prototypes, implemented in 28-nm CMOS technology, operate between 1 and 2 GHz, occupy an area of 0.51 and 0.12 mm 2 , and have a power dissipation of 32-40 and 26-64 mW, respectively. The stand-alone RX has a noise figure (NF) of 4-5 dB and an out-of-band IIP3 of 18 dBm. Turning on the passive canceller results in an effective IIP3 of 25-29 dBm and a degradation of the NF of less than 0.8 dB. Thanks to its high dynamic range, the auxiliary path suppresses the TX noise by >29 dB while degrading the RX NF by only 1 dB at 23-dBm TX output power.

Full‐duplex wireless involves simultaneous transmission and reception at the same frequency, promising significant enhancement in wireless network performance, such as spectral efficiency, link capacity, and network latency. For full‐duplex radios, >100 dB self‐interference suppression is needed and must be performed across the antenna, radio frequency (RF), analog, and digital domains. Self‐interference cancellation (SIC) in the RF domain, where a replica signal is tapped from the transmitter output and injected prior to receiver down‐conversion, has been used in many full‐duplex wireless systems. In this article, we describe different SIC architectures and unveil the challenges associated with full‐duplex RF SIC design. Discussion and review of some full‐duplex RF SIC designs are presented followed by a brief outlook for future works.
