Abstract
Duplexers for high power applications are disclosed. In some embodiments, a duplexer includes 2N band pass filters, where N is an integer greater than 1. The 2N band pass filters each have an input and an output and are in an electrically parallel configuration. The duplexer includes a first adaptation circuit configured to couple a transmit signal received from a transmitter to each one of the 2N band pass filters. The duplexer includes a second adaptation circuit configured to couple outputs of the 2N band pass filters to an antenna, the second adaptation circuit providing an isolated path between the antenna and a receiver.
