Abstract
Systems and methods for diplexer circuits with leakage cancellation are provided. In one aspect, a diplexer circuit including first and second radio frequency transceiver terminals and a first antenna terminal, and first and second parallel communication paths extending between the first radio frequency transceiver terminal and the first antenna terminal, and third and fourth parallel communication paths extending between the second radio frequency transceiver terminal and the first antenna terminal. The circuit also includes a first phase shifter configured to apply a first phase shift to a first radio frequency transmit signal on the first communication path, a second phase shifter configured to apply a second phase shift to a second radio frequency on the second communication path, and a third phase shifter configured to apply a third phase shift to the first radio frequency transmit signal on the third communication path.
