Abstract
A transceiver front end of a communication device is disclosed. The transceiver front end is connectable to a signal transmission and reception arrangement adapted to transmit a transmit signal having a transmit frequency and to receive a receive signal having a receive frequency to a transmitter adapted to produce the transmit signal and to a receiver adapted to process the receive signal. The transceiver front end 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 adapted 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 adapted to block passage of receive frequency signals between the signal transmission and reception arrangement and the transmitter. The transmit frequency blocking arrangement comprises a network of passive components comprising at least one transformer and a first filter arrangement adapted to have a higher impedance value at the transmit frequency than at the receive frequency. The receive frequency blocking arrangement comprises a second filter arrangement adapted to have a higher impedance value at the transmit frequency than at the receive frequency and a third filter arrangement adapted to have a higher impedance value at the receive frequency than at the transmit frequency.
