ABSTRACT:
An amplifier circuit has a transistor element that has an input terminal, an output terminal) and a third terminal. An input signal to be amplified is supplied to the input terminal. The amplified input signal is emitted as an output signal at the output terminal. The input terminal is connected with the output terminal via a first reactance. The third terminal is connected via a second reactance with a zero potential. One of the reactances is fashioned as an inductor and the other of the reactances is fashioned as a capacitor. An inductance value of the inductor and a capacitance value of the capacitor are dimensioned such that the quotient of the inductance value of the inductor and the capacitance value of the capacitor is equal to the product of a desired input impedance that is effective at the input terminal and an output impedance associated with the output impedance. Based on this dimensioning, the output impedance associated with the output terminal is mapped to the input terminal at the same level or scaled.
