METHOD FOR PRODUCING ENERGY INPUT/OUTPUT OF PARISON-MARKER MICROWAVE DEVICE Russian patent published in 2002 - IPC

FIELD: microwave devices; waveguide channels where stray resonant frequencies are to be eliminated. SUBSTANCE: in manufacturing mentioned devices by proposed method concave surface is made in insulating disk on at least one of its side, its radius R_b being smaller than that of insulating disk R_d so that volume of distant insulator could ensure frequency shift of stray resonance most distant from and beyond boundaries of operating frequency band. EFFECT: enhanced yield due to removal of stray resonance from operating frequency band; enhanced reliability. 2 cl, 2 dwg, 1 tbl
