摘要： A transceiver front-end of a communication device comprises a frequency blocking arrangement, which may be either a transmit frequency blocking arrangement or a receive frequency blocking arrangement. The frequency blocking arrangement has a blocking frequency interval associated with one of a transmit frequency and receive frequency, and a non-blocking frequency interval associated with the other of the transmit frequency and receive frequency. The frequency blocking arrangement is configured to block passage of signals in the blocking frequency interval between said signal transmission and reception node and either said receiver node or said transmitter node. The frequency blocking arrangement comprises a network of passive components comprising at least one transformer and a filter arrangement adapted to have a higher impedance value in the blocking frequency interval than in the non-blocking frequency interval.
