摘要： A transceiver front-end for a communication device comprises a transmit frequency blocking arrangement and a receive frequency blocking arrangement. The transmit frequency blocking arrangement has a blocking frequency interval associated with the transmit frequency and a non-blocking frequency interval associated with the receive frequency, and is configured to block passage of transmit frequency signals between the signal transmission and reception arrangement and the receiver. The receive frequency blocking arrangement has a blocking frequency interval associated with the receive frequency and a non-blocking frequency interval associated with the transmit frequency, and is configured to block passage of receive frequency signals between the signal transmission and reception arrangement and the transmitter. One of the frequency blocking arrangements comprises a network of passive components including at least one transformer and a filter arrangement with a higher impedance at the blocking frequency interval than at the non-blocking frequency interval.
