Abstract
A system and method for making a band selection in a wireless communications device is provided. The available bands include a first-communication band, a second communication band, and an auxiliary band. A wideband diplexer provides a wideband path, which includes the first-communication band and the auxiliary band, and a second-communication band path. A combination duplexer couples to the wideband path, and has an auxiliary signal port, a first-band receive port, and a first-band transmit port. A standard duplexer couples to the second communication path to provide a second-band receive port and a second-band transmit port. In one example, the first communication band is the PCS band, the second communication band is the cellular band, and the auxiliary signal is a GPS satellite signal.
