Abstract
The invention provides duplexing apparatus, wireless devices and methods for duplexing signals in which measurements are taken at multiple frequencies across a frequency band of interest, and in which a balancing impedance is controlled as a function of those measurements. Isolation between the RX and TX nodes is enhanced across the frequency band as a result.
