I-High Power Waveguide Terminations RF Microwave Load
High Power Waveguide Terminations
Umthwalo we-waveguide wamandla aphezulu uyingxenye yokungenzi lutho esetshenziselwa ukumunca amasiginali we-microwave wamandla aphezulu, ngokuvamile ebangeni lamandla angaphezu kwe-kilowatt engu-1. Zifana nokunqanyulwa kwe-waveguide yamandla amaphakathi kanye nokunqanyulwa kwe-waveguide yamandla aphansi, futhi zisetshenziselwa ukuvikela ukusebenza kwezinye izingxenye zezinhlelo ze-microwave, ukugwema ukubonakaliswa kwesignali, nokuthuthukisa ukufanisa nokuzinza kwesistimu.
Ngaphansi kwezimo zokusebenza ze-high-frequency, ukunqanyulwa kwe-coaxial okunamandla aphezulu akusakwazi ukuhlangabezana nezidingo zesistimu, ngakho-ke imithwalo ye-waveguide yamandla aphezulu yethulwa ukuze imelane namandla amaphakathi angaphezu kuka-60W. Lokhu kungenxa yokuthi amagagasi anamandla aphezulu akhiwe ngamagagasi, izinto ezimunca izinga lokushisa eliphezulu, namasinki okushisa. Ukushisa okukhiqizwa kuma-high-frequency kanye nezinhlelo ze-microwave ezinamandla amakhulu kungadluliselwa emoyeni ngokunqanyulwa kwe-waveguide, ngaleyo ndlela kugcinwe ukusebenza okuvamile nokufeza igagasi eliphansi eliphansi kanye nezici zikagesi ezizinzile.
Izici zayo zimi kanje:
1. Umthamo ophezulu wokuthwala amandla: Ukunqanyulwa kwe-RF kungamelana namasiginali wamagagasi we-microwave enamandla amakhulu namamilimitha, ngokuvamile afinyelele ububanzi bamandla obuyizinkulungwane ezimbalwa zama-watts kuya kumashumi ama-kilowatts.
2. Ukulahlekelwa kokubonisa okuphansi: Idizayini yokunqanyulwa kwe-waveguide yamandla aphezulu inengqondo, enganciphisa ngempumelelo ukulahlekelwa kokubonisa kwamasignali futhi ithuthukise ukunemba kokuhlola.
3. Ukumelana nokushisa okuphezulu: Ngenxa yesidingo sokumelana nomphumela wokushisa wamasiginali wamandla aphezulu, ukunqanyulwa kwe-waveguide ephezulu kuvame ukuklanywa ngezinto ezikhethekile nezakhiwo ukuze kube nokumelana okuhle kakhulu kwezinga lokushisa.
4. Izici ze-Broadband: Ukunqanyulwa kwe-Microwave kungasebenza ebangeni elibanzi lefrikhwensi, kulungele ukuhlola amasiginali wegagasi we-microwave enamandla amakhulu namamilimitha kumaza ahlukene.
Ezisetshenziswa ezingokoqobo, ukunqanyulwa kwe-waveguide enamandla amakhulu kuvame ukusetshenziselwa ukulinganisa izinhlelo ze-microwave zaselabhorethri, ukuhlolwa kwamandla emisebe ye-antenna kanye nemodi yemisebe, ukulawulwa kwamasiginali aphezulu ku-radar nezinhlelo zokuxhumana, ukushisisa i-microwave nokukhishwa kwe-plasma, neminye imikhakha. Afanele ukusiza ekuhloleni isistimu yamandla aphezulu, ukulungisa, nokugcinwa kahle.
Qualwaveinikeza i-broadband kanye nokunqanyulwa kwe-waveguide yamandla aphezulu, okumboza ibanga lemvamisa elingu-2.17~261GHz. Isilinganiso sokuphatha amandla singafika ku-15KW. Ukunqanyulwa kusetshenziswa kabanzi ezinhlelweni eziningi.
