<p>A transceiver front-end for a communication device is connectable at a signal transmission and reception arrangement node to a signal transmission and reception arrangement adapted to transmit a transmit signal having a transmit frequency and to receive a receive signal having a receive frequency. The transceiver front-end is also connectable at a transmitter node to a transmitter adapted to produce the transmit signal and at a receiver node to a receiver adapted to process the receive signal. The transceiver front-end comprises a transformer, wherein the transmitter node is connected to a first node of a first side of the transformer, the receiver node is connected to a first node of a second side of the transformer, and the signal transmission and reception arrangement node is connected to a second node of the first side of the transformer and to a second node of the second side of the transformer. The transceiver front-end also comprises a first tunable capacitance connected between the transmitter node and the receiver node, and a second tunable capacitance connected between the signal transmission and reception arrangement node and a signal reference level. Corresponding transceiver, communication device and method are also disclosed.</p> |
