A duplexer filter assembly, and an associated method, for a communications
device capable of operation at a frequency-band set. Separate duplexer
filters, each formed of a transmit part and a receive part, are
switchingly coupled to the communication circuitry of the communication
device. A selected one, or the other, of the duplexer filters is
connected to the communication circuitry by switch circuitry depending
upon at which parts of the communication device is to be operated.
