Abstract: A phase shifter for adjusting a phase shift between an input signal and output signal of the phase shifter includes: a first signal path between the input and the output; a second signal path between the input and the output; and a phase-shifter circuit configured to shift a phase of a first signal of the first signal path and a phase of a second signal of the second signal path by a constant phase angle relative to each other. The first and second signal paths each comprise a voltage-divider circuit connected to its respective signal path and configured to adjust an amplitude of a signal of the respective signal path. The output signal is based on a combination of the first signal and the second signal.
