MICROWAVE PHASE SHIFTER Russian patent published in 2004 - IPC

FIELD: microwave radio engineering; stepless control of electrical length of feeder lines and microwave devices. SUBSTANCE: microwave phase shifter that incorporates waveguide and dielectric insert arranged lengthwise of the latter for movement across waveguide has at least one matching unit disposed near each opposite end of dielectric insert, each of them being mounted for moving across waveguide irrespective of dielectric insert and matching unit position on other end of dielectric insert. Matching units may be made in the form of dielectric inserts. EFFECT: enlarged phase shift control range; enhanced matching characteristics of phase shifter. 2 cl, 4 dwg
