Abstract

Embodiments provide a method and apparatus for performing time division duplex communication, such as may be performed over a wireless communications network. In the embodiments a first circuit pathway is used to transmit a first radio frequency signal in a transmission mode and a second circuit pathway is used to receive a second radio frequency signal in a reception mode. In the reception mode, the first radio frequency signal is switched to an alternate circuit pathway. This may be performed by a radio frequency integrated circuit or by other control circuitry. Switching to an alternate circuit pathway reduces leakage of the first radio frequency signal into the second radio frequency signal.
