Slot Line Digital Ferrite Phase Shifter

Abstract

The report describes analytical and experimental techniques used in the development, design and construction of nonreciprocal slotline latching ferrite phase shifters for use in phased array antenna systems. A phase shifter configuration consisting of two 0.020 inch dielectric substrates (epsilon sub r = 30) surrounded by a single ferrite toroid (Trans-Tech TTI-105) with a wall thickness of 0.040 inches was shown to yield frequency independent differential phase shift of about 90 degrees/inch from 5.0 to 10.0 GHz with an accompanying insertion loss between 2 and 3 db. A 0.040 inch slot was etched longitudinally on one of the dielectric substrates to form the slotline circuit. The length of the ferrite toroid and substrates was 4.5 inches.
