Patent ID: 8660041

Claim:
A method of controlling a time division duplex (TDD) transceiver, the method comprising: providing a first circuit pathway and a separate, alternate circuit pathway of the TDD transceiver for a first radio frequency signal generated based on a local carrier signal from an oscillator such that the same frequency signal is directable through the first circuit pathway and the alternate circuit pathway; in a transmission mode for transmission of the first radio frequency signal, using the first circuit pathway of the TDD transceiver for transmission of the first radio frequency signal from an antenna coupled to the first circuit pathway; and in a reception mode for receiving a second radio frequency signal having the same frequency as the first radio frequency signal, using a second circuit pathway of the TDD transceiver for reception of the second radio frequency signal using the antenna which is also coupled to the second circuit pathway, the first circuit pathway and the second circuit pathway being separated by a first distance, the first and second circuit pathways having a common portion terminating at the antenna such that in the transmission mode, the first radio frequency signal is transmitted via the antenna without the second radio frequency signal being received via the antenna and in the reception mode, the second radio frequency signal is received via the antenna without transmitting the first radio frequency signal via the antenna, wherein, in the reception mode, the first radio frequency signal leaks for at least a portion of the reception mode and is directed to the alternate circuit pathway of the TDD transceiver to the first circuit pathway, the alternate circuit pathway being terminated in the TDD transceiver during the reception mode and thereby reducing the leakage of the first radio frequency signal into the first circuit pathway during the reception mode, the alternate circuit pathway and the second circuit pathway being separated by a second distance, the second distance being greater than the first distance such that the alternate circuit pathway has a higher attenuation factor than the first circuit pathway, with respect to the second circuit pathway, for local signal leakage resulting from at least the signal from the oscillator.
