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 eziguquguqukayo zamaza kunokuhlangabezana ngokufanelekileyo nemfuno yokunciphisa amandla omqondiso kunye nokuqinisekisa ukusebenza okuqhelekileyo kweesekethe ze-microwave.
Umgaqo wokusebenza we-attenuator eqhubekayo eguquguqukayo usekwe kwiimpawu zokusasaza zamaza ombane kwi-waveguides. Ubukhulu becala iqulathe amaza amaza, izixhobo zokuthelekisa i-impedance, kunye neebhloko zomqhubi oguquguqukayo. Xa umqondiso udlula kwi-waveguide, inxalenye yamandla ithathwa yibhloko yomqhubi, ngaloo ndlela inciphisa amandla omqondiso.
Xa ibhloko yomqhubi sisakhiwo somatshini esinokulungiswa ngesandla ngumsebenzisi, yi-rotary stepped attenuators. Ii-attenuators eziguquguqukayo ezenziwa ngesandla ngabancedisi abayimfuneko kwiinkqubo zonxibelelwano lwe-elektroniki.

Isicelo:

1. Ukuqinisekisa ukulingana kwamanqanaba omqondiso kwikhonkco lomqondiso, i-attenuators eguquguqukayo ye-waveguide inokufezekiswa ngokunciphisa amandla omqondiso.
2. Ukwandisa uluhlu oluguquguqukayo lwenkqubo kwakhona yindawo eqinile ye-rotary stepped 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, kwibhubhoratri, inyathelo elijikelezayo linokubonelela ngezakhono zohlengahlengiso oluguquguqukayo xa amandla omqondiso kufuneka atshintshwe ekusebenzeni kwezixhobo zokuvavanya. Kunxibelelwano lwe-microwave, i-attenuators eqhubekayo eguquguqukayo ingasetyenziselwa ukunyenyisa amandla omqondiso ukuqinisekisa ukuba isignali ayomelele kakhulu okanye ibuthathaka kakhulu ngexesha lothumelo.
Iingenelo ze-attenuators eziguquguqukayo 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 nokuthotywa okuphezulu koxinzelelo ukusuka kwi-0.96 ukuya kwi-500GHz. Uluhlu lokuthomalalisa yi-0~40dB.
