Abstract
A transceiver front-end is connectable to a signal transmission and reception arrangement adapted to transmit and receive with respective frequencies. The transceiver front-end comprises at least one of a transmit frequency blocking arrangement and a receive frequency blocking arrangement. For instance, the transmit frequency blocking arrangement has a blocking and non-blocking frequency interval associated with the transmit frequency and receive frequency, respectively, and is adapted to block passage of transmit frequency signals between the signal transmission and reception arrangement and the receiver. At least one of the transmit frequency blocking arrangement and the receive frequency blocking arrangement comprises a network of passive components comprising at least one transformer and a frequency translated impedance adapted to have a higher impedance value in the blocking frequency interval than in the non-blocking frequency interval.
