TEMPERATURE COMPENSATED LATCHING FERRITE PHASE SHIFTER

摘要

A nonreciprocal latching phase shifter that is compensated for changes in temperature. A pair of ferrite rectangular toroids in series connection are inserted into a rectangular waveguide and a dielectric material is inserted within the toroids with a magnetizing wire centrally disposed within the dielectric material and connected to a source of magnetizing current outside the waveguide. The ferrite material of one of the pairs of toroids has a remanent magnetization that increases with increasing temperature while the other of the pair has a remanent magnetization that decreases with increasing temperature.
