PHASE SHIFTER Russian patent published in 2018 - IPC H01P1/18 

FIELD: electricity.

SUBSTANCE: to be used to create a phase shifter. Summary of the invention consists in that the phase shifter comprises n slot bridge hybrids connected in series, where n is the number of bits of the phase shifter, 2n short-circuited sections of rectangular waveguides, the introduced phase shift of which ϕ_m=180°/2^m-1, where m = 1,2…n is the number of the phase shifter bit, as well as the microwave keys, 2n diaphragms are added to the phase shifter, made on the basis of a two-sided film-clad dielectric, with at least one microwave key installed on each of them, located between the exit arms of the slot bridge hybrids and the open ends of short-circuited sections of rectangular waveguides.

EFFECT: providing the possibility of increasing the manufacturability, simplifying the adjustment.
