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 degreesinch 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.
