Tunable duplexers based on self-interference cancellation present a promising alternative to fixed-frequency duplexers (e.g. surface acoustic wave devices), however the level of transmit-to-receive (Tx-Rx) isolation they provide is typically lower co

This paper presents a novel tunable FDD transceiver architecture which uses an electrical balance duplexer (EBD) to isolate Tx noise in the Rx band, and combines this with active self-interference cancellation to suppress the Tx blocker. This overcom
