RECIPROCAL SELF-LATCHING FERRITE DEVICES.
SYRACUSE UNIV RESEARCH CORP NY SPECIAL PROJECTS LAB
The object of this program is to investigate and develop microwave ferrite devices for phased array radar systems. The large number of elements in these systems makes it desirable to have a device configuration which can be easily and inexpensively manufactured. A suitable configuration consisting of a meanderline center conductor and a plane sheet of ferrimagnetic material formed into a microstrip or stripline transmission system was used as a building block for the ferrite devices. A qualitative explanation of the meander-lines interaction with the ferrimagnetic material is contained in the report. Two ferrite devices utilizing the meander-line configuration were constructed and tested to verify the feasibility of this geometry and determine the problem areas. Initial experimental results are reported on a latching medium peak-power non-reciprocal S-band phase shifter and a latching S-band circulator. The phase shifter was built in stripline and the circulator was built in a novel microstrip geometry.
