Abstract

A phase actuator for a continuously adjustable phase displacement at a first frequency is provided. The phase actuator has a first inductance with tapping point, a first continuously variable capacitor, and a transformation network. A signal input and a signal output of the phase shifter are connected by the first inductance. The first continuously adjustable capacitor is connected in parallel to the first inductance. The tapping point is connected via a transformation network to a reference mass, where an impedance value of the transformation network corresponds to a quarter wave transform of a capacitance value of the first continuously variable capacitance at the first frequency.
