The results of designing a phase control device in the decimeter wavelength range in the form of a tunable bandpass filter are presented. Tuning such a filter by 1/2 of the relative bandwidth, not exceeding 40 - 50%, provides a frequency-independent controlled phase shift. The minimization of parasitic amplitude modulation, along with an increase in the high-frequency power transmitted by the phase shifter, is achieved by optimizing the switching factor of the varicap into the quasi-polynomial bandpass filter circuit.
