I-Waveguide Attenuators Eguquguqukayo
Kumasekhethi e-microwave, amandla amasiginali avame ukuba phezulu kakhulu. Uma amandla amaningi engakwazi ukulawulwa ngokugcwele, angabangela kalula izinkinga eziningi kumjikelezo, njengokweqa ububanzi obuphelele bokubekezelela amandla ezingxenyeni zesekethe futhi kubangele ukuphambuka okuhlukahlukene. Ukusetshenziswa kwama-waveguide attenuators kungahlangabezana ngempumelelo nesidingo sokunciphisa amandla esignali futhi kuqinisekise ukusebenza okuvamile kwamasekhethi e-microwave.
Umgomo wokusebenza we-waveguide attenuator usekelwe ezicini zokusatshalaliswa kwamagagasi kagesi kuma-waveguides. Iqukethe ikakhulukazi ama-waveguides, amadivaysi afanayo we-impedance, namabhulokhi we-conductor ahlukahlukene. Lapho isignali idlula ku-waveguide, ingxenye yamandla imuncwa i-conductor block, ngaleyo ndlela yehlise amandla esiginali.
Uma i-conductor block iyisakhiwo somshini esingalungiswa ngesandla ngumsebenzisi, i-waveguide variable attenuators. Ama-attenuators aguquguqukayo e-waveguide angabasizi ababalulekile ezinhlelweni zokuxhumana zikagesi.
Isicelo:
1. Ukuqinisekisa ibhalansi yamazinga esignali ochungechungeni lwesignali, izibambisi ze-waveguide ezilungisekayo zingafinyelelwa ngokunciphisa amandla esignali.
2. Ukwandisa ububanzi obuguquguqukayo besistimu futhi kuyiphuzu eliqinile le-waveguide attenuator eshintshwayo ngesandla, engaqinisekisa ukusebenza okuzinzile kwesistimu.
3. Ukunikeza ukufaniswa kwe-impedance kungagwema ukubonakaliswa kwesignali nokulahlekelwa, ukuqinisekisa ukuzinza kokudluliswa kwesignali.
I-attenuator eguquguqukayo ye-waveguide isetshenziswa kakhulu ekuxhumaneni kwe-microwave nokuhlolwa kwelabhorethri. Ingasetshenziselwa ukulungisa amandla esignali ukuze ihlangabezane nezidingo ezahlukene. Isibonelo, elabhorethri, i-waveguide variable attenuator ingahlinzeka ngamakhono okulungisa avumelana nezimo lapho amandla esignali edinga ukushintshwa ukuze ahlole ukusebenza kwemishini. Ekuxhumaneni kwe-microwave, izibambisi eziguquguqukayo ze-waveguide zingasetshenziswa ukulungisa amandla esignali ukuze kuqinisekiswe ukuthi isignali ayinamandla kakhulu noma ayibuthakathaka kakhulu ngesikhathi sokudlulisela.
Izinzuzo zama-attenuators aguquguqukayo we-waveguide kulula, ukusebenzisa kalula, kanye nokulungiswa okuvumelana nezimo. Ngokusebenza mathupha, abasebenzisi bangalawula ngokunembile inani lokuncishiswa kwesignali njengoba kudingeka. Kodwa-ke, uma kuqhathaniswa ne-attenuators ye-waveguide ezenzakalelayo, ububanzi bokulungiswa kwezithonjana ze-waveguide attenuators bungase bube buncane, futhi inqubo yokulungisa idinga inani elithile lesikhathi nokunemba.
Qualwaveihlinzeka nge-VSWR ephansi kanye nokuqina okuphezulu kwe-flatness kusuka ku-0.96 kuya ku-110GHz. Ububanzi bokunciphisa bungu-0~30dB.
