Abstract:
1. A transceiver comprising: a transmitter; a receiver; a signal transmission arrangement that is arranged to transmit signals provided from the transmitter, and arranged to receive signals and provide them to the receiver; a first signal transferring element arranged between the transmitter output and the signal transmission arrangement, wherein the first signal transferring element is arranged to: a transformer comprising a first winding and a second winding being mutually magnetically connected, wherein the first winding is electrically connected in a circuit path which is connected in parallel to the first signal transferring element, and the second winding is connected to an input of the receiver; a first controller arranged to control a gain or attenuation of the first signal transferring element such that the first signal transferring element and the circuit path have equal gain or attenuation impact on signals from the transmitter; and a measurement circuit arranged to measure a signal significant for a voltage contribution from the transmitter in the first winding, wherein the first controller comprises a feedback circuit arranged to perform the control based on the measured signal such that the first signal transferring element transfers signals from the transmitter to the signal transmission arrangement and a transmitter contribution in the first winding is suppressed.
