Abstract

Multiband FDD operation requires numerous off-chip duplexers, which limit form factor. Widely-tunable low-noise RF active self-interference cancellation (SIC) (e.g. [1]) is a step towards enabling duplexers with reduced TX/RX isolation as well as adjacent-channel full duplex. However, SIC bandwidth (BW) is limited to a few MHz due to the selectivity of the high-Q duplexer isolation. Recent works suggest that same-channel full duplex (SC-FD) can greatly improve network performance [2-4]. SIC must be pursued in RF, analog/mixed-signal and digital for SC-FD to achieve the >100dB of SIC required, as filtering the SI is not an option. However, SC-FD self-interference channels can be frequency-selective due to ambient reflections [3], requiring silicon-averse bulky delay lines to replicate the delays in the RF SIC path [2].
