Wireless communication unit, radio frequency module and method therefor

摘要

A wireless communication unit includes at least one antenna port; a transmitter and a receiver operably coupled to the at least one antenna port via a duplexer; wherein the duplexer includes a dynamically reconfigurable phase shift network that includes: at least one tunable radio frequency (RF) component; and at least one switch operably coupled to the tunable RF component and controllable to reconfigure the dynamically reconfigurable phase shift network to selectively support both normal and reverse duplexer modes of operation for RF signals passing there through.

1. A wireless communication unit comprising:
at least one antenna port; and a transmitter and a receiver operably coupled to the at least one antenna port via a duplexer; wherein the duplexer comprises a dynamically reconfigurable phase shift network that comprises: at least one tunable radio frequency (RF) component, wherein the at least one tunable RF component comprises a tunable RF filter coupled to one of a receive chain and a transmitter chain of the wireless communication unit; and at least one switch operably coupled to the tunable RF component and controllable to reconfigure the dynamically reconfigurable phase shift network in response to duplex modes of operation comprising normal and reverse duplexer modes of operation so as to selectively support both the normal and reverse duplexer modes of operation for RF signals passing there through; wherein the at least one switch is controllable to selectively provide at least one signal transmission path between the tunable RF filter and the at least one antenna port in response to the duplex modes of operation; and the tunable RF filter is coupled in series between the at least one antenna port and the one of the receive chain and the transmitter chain in both the normal and reverse duplexer modes of operation.
