A radio front end includes a duplexer, a tunable balancing network, a detector module, and a processing module. The duplexer is operably coupled to an antenna and is operable to provide electrical isolation between an outbound wireless signal and an inbound wireless signal. The tunable balancing network is operably coupled to the duplexer and operable to establish an impedance that substantially matches an impedance of the antenna based on a tuning signal. The detector module is operable to generate an error signal based on an electrical performance characteristic of the duplexer. The processing module is operable to generate the tuning signal based on the error signal.
