Abstract
This paper is the next one in the series of studies on the methods of resonance measuring and parameter checking of ferrite elements in a microwave device [1-3], that enables measuring and controlling both the electromagnetic parameters of ferrites and their magnetic “activity”. This can be achieved by measuring the loaded Q-factor and the magnitude of the operating resonance tuning of the ferrite sample in a measuring box (MB), exposed to an external magnetic bias. The properly chosen magnitude of the magnetic bias plays a significant role in the screening procedure, as it impacts the quality of measuring the ferrite tensor components and sorting of ferrite elements being parts of various types of real microwave devices. The paper offers a description of the MB design and the technique of a non-invasive screening of ferrite elements of the phased arrays (PA).
