Claim 0:
1. A duplexer circuit comprising:
a transmit path splitter configured to split a radio frequency transmit signal into a pair of radio frequency transmit signals, and a receive path splitter configured to combine a pair of radio frequency receive signals;
an antenna path splitter configured to combine a pair of radio frequency transmit signals and split a radio frequency receive signal into the pair of radio frequency receive signals; and
first and second duplexers, the first duplexer coupled to a first leg of each of the transmit path splitter, the receive path splitter, and the antenna path splitter, and the second duplexer coupled to a second leg of each of the transmit path splitter, the receive path splitter, and the antenna path splitter, the antenna path splitter configured to coherently sum the pair of radio frequency transmit signals, the receive path splitter configured to coherently sum the pair of radio frequency receive signals, and the receive path splitter further configured to destructively cancel leakage of the pair of radio frequency transmit signals through the first and second duplexers.
