Patent ID: 7095985

Claim:
A radio transceiver comprising: a transmitter output stage; a receiver part; a transmission/reception antenna which is jointly assigned to the transmitter output stage and the receiver part; a transmission band-transmitting filter which is connected between the output of the transmitter output stage and an antenna feedpoint; a reception band-transmitting filter which is connected between the antenna feedpoint and the input of the receiver part; a compensation element which is connected between the output of the transmitter output stage and the input of the receiver part and compensates crosstalk from a transmission signal element onto the receiver part; and a compensation control unit to adaptively set compensation characteristics as a function of the input voltage or input power at the input of the receiver part being assigned to the compensation element, wherein a voltage measuring device which is connected to the compensation control unit measures the input voltage of the receiver part, the voltage measuring device comprising a device for IF conversion of the input signal of the receiver part, a bandpass filter which is connected downstream and an AM receiver part which is connected to its output and whose output is used to set the compensation characteristics.
