Abstract
A new reciprocal ferrite phase-shifter in 4 millimeter wavelength is described. This electronically controlled phaser uses a reduced height rectangular waveguide and the ferrite material is longitudinally magnetized. A theoretical approach of the problem from the coupled-mode formalism is elaborated. The first performances of a 90/spl deg/ phaser element at 70 GHz are obtained with 1.5 db maximum insertion loss and a VSWR < 1.5. That corresponds to a figure of merit equal to 60 deg/db. The measured characteristics of the phaser show good agreement with computational values.
