Dual-mode latching ferrite devices
Abstract
A primary consideration with microwave ferrite control devices is related to the switching speed. In order to achieve fast switching with the considered devices, an operation in the latching mode is required. A description is given of a new class of ferrite latching devices, taking into account latching quadrupole devices and their modifications. It is pointed out that the advantages of the new devices include fast switching, high electrical performance, and simple construction. According to the utilization of external or internal magnetic return paths, there are two modes of operation in latching ferrite devices. Attention is given to constructions and calculations, the design of a model for each of the two modes of operation, polarization insensitive phase shifters (PIPS) with external magnetic return paths, and PIPS with internal magnetic return paths.
