Beschreibung
Zusammenfassung:	A device may include a receive antenna input to couple a receive chain of the device to a receive antenna. The device may include a test signal generator. The device may include a switchable impedance matching circuit coupled to the test signal generator and to the receive chain to cause an impedance matching between the test signal generator and at least one component of the receive chain to depend on an impedance of the receive antenna in an antenna monitoring phase. The antenna monitoring phase may be associated with determining an impedance mismatching of the receive antenna. The device may include a control circuit to determine the impedance mismatching of the receive antenna in the antenna monitoring phase.
