Izithinteli eziguquguqukayo zeWaveguide

Kwiisekethe ze-microwave, amandla emiqondiso adla ngokuba phezulu kakhulu. Ukuba amandla agqithisileyo awakwazi ukulawulwa ngokupheleleyo, kuya kubangela iingxaki ezininzi kwisekethe, njengokugqitha uluhlu oluphezulu lokunyamezela amandla lwezixhobo zesekethe kwaye kubangele ukuphambuka okuhlukeneyo. Ukusetyenziswa kwee-waveguide variable attenuators kunokuhlangabezana ngempumelelo nemfuno yokunciphisa amandla esignali kwaye kuqinisekise ukusebenza okuqhelekileyo kweesekethe ze-microwave.
Umgaqo osebenzayo we-attenuator eguquguqukayo ngokuqhubekayo usekelwe kwiimpawu zokusasazeka kwamaza e-electromagnetic kwi-waveguides. Ngokuyintloko iqulathe ii-waveguides, izixhobo zokulinganisa i-impedance, kunye neebhloko ze-conductor eziguquguqukayo. Xa isignali idlula kwi-waveguider, inxalenye yamandla ifunxwa yi-conductor block, ngaloo ndlela inciphisa amandla esignali.
Xa ibhloko yomqhubi wemoto iluhlobo lomatshini olunokulungiswa ngesandla ngumsebenzisi, luyi-rotary stepped attenuators. Ii-handed variable attenuators ziluncedo kakhulu kwiinkqubo zonxibelelwano lwe-elektroniki.

Isicelo:

1. Ukuqinisekisa ibhalansi yamanqanaba esignali kwikhonkco lesignali, ii-waveguide variable attenuators zinokufezekiswa ngokunciphisa amandla esignali.
2. Ukwandisa uluhlu oluguquguqukayo lwenkqubo kukwayindawo eqinileyo ye-attenuator ejikelezayo, enokuqinisekisa ukusebenza okuzinzileyo kwenkqubo.
3. Ukubonelela ngokuthelekiswa kwe-impedance kunokuthintela ukubonakaliswa kwesignali kunye nokulahleka, ukuqinisekisa uzinzo lokudluliselwa kwesignali.

I-waveguide variable attenuator isetyenziswa kakhulu kunxibelelwano lwe-microwave kunye novavanyo lwelebhu. Ingasetyenziselwa ukulungisa amandla esignali ukuze ihlangabezane neemfuno ezahlukeneyo. Umzekelo, kwilebhu, i-rotary step inokubonelela ngezakhono zokulungisa eziguquguqukayo xa amandla esignali kufuneka atshintshelwe ukuvavanya ukusebenza kwezixhobo. Kunxibelelwano lwe-microwave, ii-continuously variable attenuators zingasetyenziselwa ukulungisa amandla esignali ukuqinisekisa ukuba isignali ayinamandla kakhulu okanye ayibuthathaka kakhulu ngexesha lokudluliselwa.
Iingenelo zee-attenuators eziguquguqukayo kukulula, ukusebenziseka lula, kunye nohlengahlengiso oluguquguqukayo. Ngokusebenza ngesandla, abasebenzisi banokulawula ngokuchanekileyo ubungakanani bokunciphisa isignali njengoko kufuneka. Nangona kunjalo, xa kuthelekiswa nee-attenuators ze-waveguide ezizenzekelayo, uluhlu lohlengahlengiso lwee-attenuators ze-waveguide ezisetyenziswa ngesandla lunokuba luncinci, kwaye inkqubo yohlengahlengiso ifuna ixesha elithile kunye nokuchaneka.

I-Qualwaveibonelela nge-VSWR ephantsi kunye nokuqina okuphezulu kokunciphisa ukusuka kwi-0.96 ukuya kwi-500GHz. Uluhlu lokunciphisa yi-0 ~ 40dB.
