A duplexer includes a duplexer package having a transmit terminal, an antenna terminal, a receive terminal and at least one package ground terminal, a transmit filter disposed within the duplexer package, and a receive filter disposed within the duplexer package. Coupled first and second inductors, the first inductor connected to the transmit filter and the second inductor connected to the receive filter, are configured to cancel, at least in part, RF signal leakage between the transmit filter and the receive filter.
