Claim 12:
13. A method of duplexing radio frequency signals, the method comprising:
outputting first and second radio frequency transmit signals onto respective first and second parallel transmit paths extending between a power amplifier and an antenna;
applying a first phase shift to the first radio frequency transmit signal between the power amplifier and a first duplexer on the first transmit path;
outputting first and second radio frequency receive signals onto respective first and second parallel receive paths extending between the antenna and a receive splitter;
applying a second phase shift to the first radio frequency receive signal between the antenna and a second duplexer on the first receive path; and
applying a third phase shift to the second radio frequency receive signal between the first duplexer and the receive splitter on the second receive path.
