| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a magnetron capable of effectively suppressing a plurality of harmonic components with a simple configuration.SOLUTION: A magnetron 1 includes a choke part 60 which is constituted of a first choke 30 and a second choke 32 which are a plurality of chokes formed inside of a metal sealing body 7 in an output part 5 for suppressing harmonic. The frequency in the choke part 60 is different from that of the metal sealing body 7. A plurality of choke grooves 31A, 31B and 31C are formed which correspond respectively to the harmonic components the number of which is greater than the number of the first choke 30 and the second choke 32.SELECTED DRAWING: Figure 2
【課題】簡易な構成で複数の高調波成分を効果的に抑制する。【解決手段】マグネトロン１は、出力部５における金属封着体７の内側に設けられた複数のチョークである第１チョーク３０及び第２チョーク３２により構成され高調波を抑制するチョーク部６０を設け、チョーク部６０と、金属封着体７とによって、周波数が異なり第１チョーク３０及び第２チョーク３２の個数よりも多い高調波成分のそれぞれに対応する複数のチョーク溝３１Ａ、３１Ｂ及び３１Ｃが形成されるようにする。【選択図】図２ |
