Abstract
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.
