Abstract
A high-frequency phase shifter for varying the phase between its high-frequency input signal and its output signal by the transmission phase Φ, consisting of a two-port network which is symmetrical in relation to input and output and which with respect to its high-frequency properties consists of three two-terminal networks consisting of low-loss reactances, wherein at least one of the two-terminal networks is arranged in a series circuit as a two-terminal network in series with one of the connecting ports and at least one of the two-terminal networks is arranged in a parallel circuit as a two-terminal network in parallel with the two-port earth, so that a symmetrical T-circuit or a symmetrical π circuit is provided.
