Abstract : In the microwave region of the electromagnetic spectrum, electronically controllable ferrite phase shifters have demonstrated their value as components and as control elements for switches and attenuators. As the need for control components operating in the lower millimeter wave region increases, it is a reasonable approach to scale successful microwave ferrite configurations into the lower millimeter wave region (30 GHz to 140 GHz). However, many problems are encountered when attempting to scale efficient microwave ferrite configurations, particularly latching ferrite configurations, into the millimeter wave region. It is the objective of this report to review several ferrite configurations with the intent that consideration of these configurations may stimulate development of practical millimeter wave configurations. Ferrite phase shifter configurations that will be the subject of comment include the toroidal (dual slab), dual mode, Bush-Reggia-Spencer, and single slab configurations. Comments are also presented on a circulator used as a phase shifter. (Author)
