Abstract:
A method for the impedance matching of front end circuits to antennas in mutually different transmission and reception frequency ranges is specified. A suitable matching circuit is furthermore specified. The impedance matching in a transmission frequency range is determined such that an excessively poor impedance matching in a reception frequency range is prevented in this case.
