Abstract
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.
Claims17
A transmitting arrangement comprising
- a matching circuit comprising an adjustable impedance;
- a reference circuit comprising a reference impedance and an input, and configured for the input to be coupled to an input of the matching circuit, and
- a comparator comprising a first input, a second input and an output, and configured to be coupled to the matching circuit via the first input, to the reference circuit via the second input and to the adjustable impedance of the matching circuit via the output.
A method for impedance matching, comprising:
- supplying a transmitting signal to a reference circuit and a matching circuit,
- generating a nominal signal,
- generating an actual signal,
- comparing the nominal signal and the actual signal, and
- adjusting an adjustable impedance based on the comparison of the nominal signal and the actual signal.
