Abstract
A transceiver front-end for a communication device 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. The transceiver front-end is also connectable 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 suppression filter arrangement and a receive frequency suppression filter arrangement. The transmit frequency suppression filter arrangement is adapted to suppress transfer of a signal having the transmit frequency and to pass a signal having the receive frequency. The receive frequency suppression filter arrangement is adapted to suppress transfer of a signal having the receive frequency and to pass a signal having the transmit frequency. The transceiver front-end also comprises a transmit frequency cancellation arrangement and a receive frequency cancellation arrangement. The transmit frequency cancellation arrangement is adapted to produce a first cancellation signal for cancellation, at receiver nodes, of a suppressed signal h…
