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-attenuators aguquguqukayo e-waveguide kungahlangabezana ngempumelelo nesidingo sokunciphisa amandla esignali futhi kuqinisekise ukusebenza okuvamile kwamasekhethi e-microwave.
Umgomo wokusebenza we-attenuator eguquguqukayo ngokuqhubekayo ususelwa ezicini zokusakazeka zamagagasi kagesi kumagagasi amagagasi. 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 ibhulokhi yekhondatha iyisakhiwo somshini esingalungiswa mathupha ngumsebenzisi, i-rotary stepped attenuators. Ama-attenuators aguquguqukayo ngesandla angabasizi ababalulekile ezinhlelweni zokuxhumana zikagesi.

Isicelo:

1. Ukuqinisekisa ibhalansi yamazinga esignali kuchungechunge lwesignali, izibambisi eziguquguqukayo ze-waveguide zingafinyelelwa ngokunciphisa amandla esignali.
2. Ukwandisa ububanzi obuguquguqukayo besistimu futhi kuyiphuzu eliqinile le-rotary stepped attenuator, 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, isinyathelo esijikelezayo singanikeza amandla okulungisa avumelana nezimo lapho amandla esignali edinga ukushintshwa ukuze ahlole ukusebenza kwemishini. Ekuxhumaneni kwe-microwave, izibambisi ezishintshayo eziqhubekayo zingasetshenziswa ukulungisa amandla esignali ukuze kuqinisekiswe ukuthi isignali ayinamandla kakhulu noma ayibuthakathaka kakhulu ngesikhathi sokudlulisela.
Izinzuzo zama-attenuators aguquguqukayo ubulula, ukusebenziseka kalula, 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-500GHz. Ububanzi bokunciphisa bungu-0~40dB.
