Abstract:
A transceiver suitable for frequency division duplex (FDD) communication is disclosed. In one exemplary embodiment, a transmitter leakage reduction circuit for a transceiver is described. The transmitter leakage reduction circuit comprises an auxiliary power amplifier, first and second filters, and a signal transmission arrangement. The auxiliary power amplifier is configured to provide an auxiliary power amplifier output signal that represents an output signal of a power amplifier of the transmitter with a controllable phase shift or gain output. The first and second filters are configured to attenuate any signals in the receive frequency band of the respective power amplifier output signal and auxiliary power amplifier output signal. The signal transmission arrangement is configured to suppress a contribution of the power amplifier output signal from a signal received from an RF connecting point using the auxiliary power amplifier output signal to obtain a received signal that is input to the receiver.

Claim (Index 20):
A transceiver capable of operating in a frequency division duplex (FDD) communications system having transmit and receive frequency bands, the transceiver comprising:\n a radio frequency (RF) connecting point that is capable of being coupled to an antenna; a receiver; a transmitter having a power amplifier that is coupled to the RF connecting point; and a transmitter leakage reduction circuit comprising:\n an auxiliary power amplifier configured to provide an auxiliary power amplifier output signal that represents an output signal of the power amplifier with a controllable phase shift or gain output; \n a first filter coupled between the power amplifier and the RF connecting point, the first filter configured to attenuate any signals in the receive frequency band of the power amplifier output signal; \n a second filter coupled to the auxiliary power amplifier and configured to attenuate any signals in the receive frequency band of the auxiliary power amplifier output signal; and \n a signal transmission arrangement coupled between the first and second filters and between the RF connecting point and the receiver, the signal transmission arrangement configured to suppress a contribution of the power amplifier output signal from a signal received from the RF connecting point using the auxiliary power amplifier output signal to obtain a received signal that is input to the receiver.
