Abstract
A transceiver comprises a receiver, a transmitter, a signal transmission arrangement, a first signal transferring element, and a transformer having magnetically-connected first and second windings. The first signal transferring element is between the transmitter output and the signal transmission arrangement, which is arranged to transmit signals from the transmitter and to receive signals and provide them to the receiver. The first winding of the transformer is connected in parallel with the first signal transferring element, which has input and output impedances so that signals from the transmitter output reach the signal transmission arrangement, while signals from the signal transmission arrangement do not reach the transmitter output. As such, the first signal transferring element is arranged to transfer signals from the transmitter to the signal transmission arrangement such that the transmitter contribution to the signal in the first winding is suppressed.
