The modern schemes of phase shifters used in radio receivers, antenna systems, synchronous detectors are limited in a wide frequency range to dependence of phase shift at the release of the scheme from the frequency of an entrance signal. In this work the new scheme of the programmable phase shifter which allows to use the phase shifter in the wide frequenciest range irrespective of the frequency of an entrance signal and also to carry out a phase displacement with a high precision is offered.

Keywords: phase shifter, synchronous detector, lag line
