Abstract
An integrated duplexer and combiner in a telecommunication system, such as a cross-polarized antenna system, is disclosed. An integrated duplexer and combiner may result in a reduction in the number of transmit filters used. A transmit filter may be coupled to two receive filters through a transmission network that provides isolation between the two receive signal paths and, at the same time, provide power splitting of transmitter power to two duplexed transmit signal paths. The transmission network includes first and second λ/4 transmission lines coupled between inputs of the two receive filters. A third λ/4 transmission line couples the first and second λ/4 transmission lines to an output of the transmit filter. The two receive filters may have the same passband, while the transmit filter may have a different passband.
