METHOD FOR TUNING WAVEGUIDE THREE-ARM FERRITE CIRCULATOR TO MATCHING TRANSFORMER Russian patent published in 1997 - IPC

FIELD: decoupling devices which are based on waveguide three-arm ferrite circulators. SUBSTANCE: method involves mounting tuning elements on wide wall of each arm of waveguide three-arm ferrite circulator and on end of matching transformer in middle of each arm, sending single microwave signal to each arm under influence of external magnetic field, tuning it by means of longitudinal movement of tuning element, moving additional tuning element while other tuning elements in other arms are kept in same position. Desired levels of reverse losses are set by means of subsequent movement of tuning elements which are located on end of matching transformer under influence of external magnetic field. EFFECT: increased functional capabilities.
