    摘要： The present relates to a Radio Frequency (RF) front end for wireless communications, in particular for use in a Half Duplex (HD) and/or Full Duplex (FD) transceiver. The RF front end of the invention is especially based on a Quadrature Balanced Power Amplifier (QBPA). The RF front end comprises an antenna port for outputting a transmit signal to and receiving a receive signal from an antenna, and a receive port for outputting the receive signal to a signal processing section. Further, it comprises the QBPA, which is configured to: receive a transmit input signal at a first port, receive a cancellation input signal at a fourth port, and receive the receive signal at a second port connected to the antenna port. Further, the QBPA is configured to generate the transmit signal from the transmit input signal and output the transmit signal at the second port, and generate a cancellation signal from the cancellation input signal and output the cancellation signal and the receive signal at a third port connected to the receive port.
