Abstract
A circuit provided for impedance matching includes an input, an output and four impedance elements arranged between them. In this case, two of the impedance elements are connected in series in a main path and form a T configuration with a third component. In addition, a fourth component is connected in parallel with the main path of the circuit. By way of example, the components arranged in the main path are variable capacitances and the further components are inductances.
