ABSTRACT:
A transceiver with interference signal rejection has a transmission path and a reception path. The transmission path is connected to a transmission amplifier whose output is coupled to an antenna. In addition, the antenna is also connected to the reception path. A compensating apparatus is provided which is coupled to an input of the reception path. The output of the transmission path and the input of the transmission amplifier also have an extraction element connected between them which is connected to an input of the compensating circuit. A signal component of a transmitted signal is extracted before amplification to an output level and is routed to the reception path via the compensating circuit such that this compensates for a crosstalk transmitted signal component.
