Feasibility Study of a Non-Reciprocal Latched Ferrite Phase Shifter in the 92-96 GHz Frequency Band (Studie Betreffende de Realiseerbaarheid van een niet Reciproke Schakelbare Ferriet Fasedraaier in de 92-96 GHz Frequentieband)

Abstract

A cylindrical lithium ferrite rod with a diameter of 1.27 mm and an axial hole of 0.25 mm was placed in the middle of a standard waveguide. Because of mechanical uncertainties we chose for a ferrite length of 10 mm. The average differential saturation phase shift at 92-96 GHZ is 92.5 degrees. Over a 4 GHZ frequency band the differential saturation phase shift is independent of frequency. The insertion loss of 1.5-2.5 dB can be improved. The rise time of the 905 saturation pulse is 100 nsec, the pulse length is 650 nsce and the fall time is 950 nsec. Keywords: Ferrite phase shifter, Feasibility studies, Lithium ferrite, Non-reciprocal, Netherlands.
