IiAttenuators eziguquguqukayo zeVSWR ezisezantsi
I-Waveguide eguquguqukayo i-Attenuators
Kwiisekethe ze-microwave, amandla emiqondiso ahlala ephezulu kakhulu. Ukuba amandla agqithisileyo akakwazi ukulawulwa ngokupheleleyo, kuya kubangela lula iingxaki ezininzi kwisekethe, njengokudlula uluhlu oluphezulu lokunyamezela amandla amacandelo esekethe kunye nokubangela ukutenxa ngeendlela ezahlukeneyo. Ukusetyenziswa kwee-attenuators ze-waveguide kunokuhlangabezana ngokufanelekileyo nemfuno yokunciphisa amandla omqondiso kunye nokuqinisekisa ukusebenza okuqhelekileyo kweesekethe ze-microwave.
Umgaqo wokusebenza we-waveguide attenuator usekwe kwiimpawu zokusasaza zamaza ombane kwi-waveguides. Ubukhulu becala iqulathe i-waveguides, izixhobo zokuthelekisa i-impedance, kunye neebhloko eziguquguqukayo zomqhubi. Xa umqondiso udlula kwi-waveguide, inxalenye yamandla ithathwa yibhloko yomqhubi, ngaloo ndlela inciphisa amandla omqondiso.
Xa ibhloko ye-conductor sisakhiwo somatshini esinokulungiswa ngesandla ngumsebenzisi, yi-waveguide variable attenuators. I-waveguide variable attenuators ngabancedisi abayimfuneko kwiinkqubo zonxibelelwano lwe-elektroniki.
Isicelo:
1. Ukuqinisekisa ukulingana kwamanqanaba omqondiso kwikhonkco lomqondiso, i-waveguide attenuators ehlengahlengiswayo ngesandla inokufezekiswa ngokunciphisa amandla omqondiso.
2. Ukwandisa uluhlu oluguquguqukayo lwenkqubo kwakhona yindawo eyomeleleyo ye-waveguide manual attenuator, enokuqinisekisa ukusebenza okuzinzile kwenkqubo.
3. Ukubonelela ngokuhambelana ne-impedance kunokuphepha ukubonakalisa umqondiso kunye nokulahlekelwa, ukuqinisekisa ukuzinza kokuhanjiswa kwesignali.
I-waveguide variable attenuator isetyenziswa ngokubanzi kunxibelelwano lwe-microwave kunye novavanyo lwebhubhoratri. Ingasetyenziselwa ukulungisa amandla omqondiso ukuhlangabezana neemfuno ezahlukeneyo. Ngokomzekelo, kwilabhoratri, i-attenuator eguquguqukayo ye-waveguide inokubonelela ngesakhono sohlengahlengiso oluguquguqukayo xa amandla omqondiso kufuneka atshintshwe ukuze avavanye ukusebenza kwezixhobo. Kunxibelelwano lwe-microwave, ii-attenuators eziguquguqukayo ze-waveguide zingasetyenziselwa ukunyenyisa amandla ophawu ukuze kuqinisekiswe ukuba isignali ayomelele kakhulu okanye ibuthathaka kakhulu ngexesha lothumelo.
Izibonelelo ze-attenuators eziguquguqukayo ze-waveguide zilula, kulula ukuyisebenzisa, kunye nohlengahlengiso oluguquguqukayo. Ngokusebenza ngesandla, abasebenzisi banokulawula ngokuchanekileyo inani lokuthomalalisa umqondiso njengoko kufuneka. Nangona kunjalo, xa kuthelekiswa ne-attenuators ye-waveguide ngokuzenzekelayo, uluhlu lohlengahlengiso lwe-attenuators ye-waveguide manual lunokuba luncinci, kwaye inkqubo yohlengahlengiso ifuna ixesha elithile kunye nokuchaneka.
QualwaveIbonelela nge-VSWR ephantsi kunye nokuqina okuphezulu kokuthomalalisa ukusuka kwi-0.96 ukuya kwi-110GHz. Uluhlu lokuthomalalisa yi-0~30dB.
