Abstract
The band-stop filters which resonate at intervals of one-quarters, and three-quarters guide-wave length are designed and its frequency characteristics are measured. 2K25 klystrons (at 8000MC) were used as microwaves source. This bandstop filters were designed from low pass prototype and the Impedance of Impedance of these filters was made to be equal to one of the low pass prototype. It is demonstrated that the filters considered here, have narrow stop bandwidths and sharp characteristics in the stop band.
저역통과여파기로부터 대역저지 여파기를 유도하여 그의 등가회로를 그렸으며 각각의 임피이던스가 같음을 증명하였다. 그리고 도파관 벽에 1/4λg, 3/4λg의 간격으로 공진기를 부가한 대역저지 여파기를 설계 제작하여 실험하였다. 이 실험에서 매우 좁은 대역의 통과를 저지시킬 수 있음을 알았다.
