Umkhawulo

I-limiter idivayisi ye-electronic esetshenziselwa ukukhawulela ukuphakama kwesiginali phakathi kwebanga elithile ukuze kuvinjelwe ukugcwala kwesignali noma ukuhlanekezela.Basebenza ngokusebenzisa inzuzo eguquguqukayo kusiginali engenayo, behlisa i-amplitude yayo uma yeqa umkhawulo onqunywe kusengaphambili noma umkhawulo.I-Limiter iyisifinyezo esizilawulayo kanye nemoduli yamandla.Uma amandla okufakwayo esignali emancane, akukho ukuncishiswa.Uma amandla okokufaka enyuka abe inani elithile, ukuncishiswa kuzokhula ngokushesha.Leli nani lamandla libizwa nge-threshold level.

Izici zomkhawulo wethu we-RF zihlanganisa:

I-1.Isikhawuli sesivinini esiphezulu: singaphendula ngokushesha futhi sicubungule amasiginali aphezulu, ukuze isignali igcinwe ebangeni eliphephile.
I-2.Ukuhlanekezela okuphansi: kungalawula ngempumelelo i-amplitude yesiginali, ukuqinisekisa ukuthi isignali ngeke ibonakale ihlanekezela kanye nokulimala.
3.Izici ze-Broadband: imvamisa engu-0.03 ~ 18GHz, ingacubungula amasiginali ahlukahlukene.
I-4.Ukunemba okuphezulu: ukuphakama kwesiginali kungalawulwa ngokunembile ukuze kuqinisekiswe ukuthi ukucubungula isignali kunembile ngangokunokwenzeka.
5.Ukusetshenziswa kwamandla okuphansi: amandla angu-5 ~ 10w ikakhulukazi, awenza abe wusizo kakhulu ezinhlelweni zokusebenza zemvamisa ephezulu ngaphansi kokuvinjelwa kokunikezwa kwamandla kamakhalekhukhwini.
I-6.Ukuzinza okuphezulu: I-beam ingagcina ukusebenza okuzinzile ngaphansi kwezinguquko zokushisa nezinye izimo zemvelo, ngakho-ke ifaneleka kakhulu izicelo eziyinkimbinkimbi.

Okulandelayo ezinye izinhlelo zokusebenza ze-limiter:

I-1.Vikela ama-circuits namadivayisi: I-Limiter ingasetshenziswa ukuvikela ama-circuits namadivayisi kusuka kuma-amplitudes esignali aphezulu.Uma isignali yokokufaka idlula umkhawulo, isikhawuli sizokhawulela i-amplitude yesiginali phakathi kwebanga eliphephile ukuvimbela ukugcwala kwesignali kanye nokulimala kudivayisi.
2. Ukucutshungulwa komsindo: I-Limiter isetshenziswa kakhulu ekucubungulweni komsindo.Isibonelo, ekurekhodweni komculo nasezisetshenziswani zokudlala, isikhawuli singasetshenziswa ukulawula ububanzi obuguquguqukayo besiginali yomsindo, ukuze ubukhulu besiginali yomsindo bube phakathi kwebanga elamukelekayo, kuvinjwe ukugcwala kwesignali yomsindo noma ukuhlanekezela.
3. Isistimu yokuxhumana: Kuhlelo lokuxhumana, umkhawulo ungasetshenziswa ukulungisa ubude nobubanzi obuguqukayo besignali ukuze kuqinisekiswe ukuthi isignali aweqi umkhawulo wesilinganiso sesignali-kuya-nomsindo ngesikhathi sokudlulisa, ukuthuthukisa ikhwalithi nokuthembeka ukuxhumana.
4. Ukucutshungulwa kwevidiyo: I-Limiter nayo ivame ukusetshenziswa ekucutshungulweni kwevidiyo.Isibonelo, kumakhamera wevidiyo nezinhlelo zokuqapha, i-limiter ingasetshenziswa ukulawula ukuphakama kwesignali yevidiyo, ukuze ukukhanya nokugqama kwesithombe kungaphakathi kwebanga elifanele, ukuthuthukisa ukucaca nokubonakala kwesithombe.
5. Ukulinganisa okunembayo: Kwezinye izindawo zokulinganisa ukunemba, umkhawulo ungasetshenziswa ukulawula i-amplitude yesiginali yokufaka ukuze kuqinisekiswe ukunemba nokuzinza kwemiphumela yokulinganisa.Isibonelo, kumathuluzi okulinganisa anembe kakhulu, isikhawuli singagwema amaphutha okulinganisa abangelwa amasignali okokufaka angaphandle kwebanga.

QualwaveI-Inc. ihlinzeka ngemikhawulo ngebanga lefrikhwensi engu-0.03~12GHz, elungele okungenantambo, isidluliseli, irada, ukuhlolwa kwaselabhorethri nezinye izindawo.
