Nova Microwave staff has a thorough understanding of the working of ferrite and magnet materials and their application to develop electronic microwave circulators and isolators. The selection of basic ferrite material and magnet material has a significant effect on the overall performance and cost of circulators and isolators. The power handling, insertion loss, and labor required to manufacture these circulators and isolators is very dependent on this material selection. The ferrite material and magnet material required for circulators and isolators; is a major cost contributor to the final circulator and isolator cost. Nova designers have developed custom programs to provide the optimum performance at the lowest cost. The detailed understanding of the circulators and isolators is as follows:
