    摘要: A transmission arrangement for modulating useful signals onto a carrier frequency signal has a frequency generator for generating the carrier frequency signal, a first modulation path for modulating a first useful signal onto the carrier frequency signal, and a second modulation path for modulating a second useful signal onto the carrier frequency signal. The first modulation path has a digital modulator for providing an amplitude signal and a Cartesian signal pair from the first useful signal and a Cartesian modulator for modulating the Cartesian signal pair onto the carrier frequency signal in order to provide an intermediate signal. The first modulation path is configured in such a manner that the amplitude signal is modulated onto the intermediate signal in order to provide an output signal.

    摘要: A transmitting arrangement includes a matching circuit, a reference circuit and a comparator. The output of the matching circuit can be coupled to an antenna and comprises an adjustable impedance. The reference circuit is connected to an input of the matching circuit and comprises a reference impedance. Inputs of the comparator are coupled to the matching circuit and the reference circuit and its output is coupled to the adjustable impedance via a control input of the matching circuit.
