ABSTRACT:
A multiport phase shifter for microwave energy provides four output components of an input wave each shifted a prescribed amount in phase, in an enclosure having two plates held together by studs mounted on one of them for locating a power divider and four independent phase-shift branches, and independent diode mounts for each, and for spacing the plates the correct distance to serve as ground planes for TEM-mode lines within the enclosure. Phase trimmers at each output port serve to adjust the output phase relations to a specification without requiring any invasion of the enclosure.
