Barend van Liempd, Benjamin Hershberg, Nathalie Fievet
The present disclosure provides a telecommunications device comprising an electrical balance duplexer connected to an output node of a transmission path, an input node of a receive path, an antenna and a tuneable impedance. The electrical balance duplexer is configured to isolate the transmission path from the receive path by tuning the tuneable impedance by means of a tuning circuit. The tuning circuit comprises voltage amplitude detectors at the connections between the electrical balance duplexer and the transmission path, the receive path and the tuneable impedance, voltage phase ...
