Ii-Attenuators eziLawulwa yiVoltage Ulawulo lweVoltage Ulawulo lwe-Analog oluguquguqukayo
Ii-voltage controlled attenuators zizixhobo zesekethe ezidibeneyo ezinokulawula inqanaba lokuncitshiswa kwemiqondiso yazo yokukhupha ngokusebenzisa imiqondiso ye-voltage yokungenisa yangaphandle. Iimpawu zayo eziphambili kunye nokusetyenziswa kwazo zezi zilandelayo:
Iimbonakalo:
1. Ukulungelelaniswa: Izithinteli zolawulo lweVolthi zilungisa inqanaba lokuncitshiswa kwesignali yazo yokukhupha ngokusebenzisa imiqondiso yevolthi yokungenisa yangaphandle, nto leyo evumela ukulungiswa nolawulo oluchanekileyo.
2. Umgca ophezulu: Kukho ubudlelwane obuphezulu obuphakathi kombane wokufaka kunye nokuncitshiswa kwemveliso, okwenza ii-attenuators ze-voltage variable zichaneke kakhulu kwaye zizinzile kwizicelo ezisebenzayo.
3. I-bandwidth ebanzi: Ii-attenuators ezilawulwa yi-analog zinempendulo entle ethe tye kuluhlu lwee-frequency, ngoko ke zinokusetyenziswa kuluhlu olubanzi lweesignali ze-frequency.
4. Ingxolo ephantsi: Ngenxa yokusetyenziswa kwezinto ezinengxolo ephantsi kuyilo lwangaphakathi lwesekethe yee-attenuators zolawulo lwe-analog, ii-attenuators ezilawulwa yiVoltage zibonisa izalathisi zengxolo ephantsi kakhulu ngexesha lokusebenza.
5. Ukuhlanganiswa: Ii-attenuators ezilawulwa yi-voltage zinokudityaniswa kwezinye iisekethe, nto leyo ebangela ukuba ivolumu ibe ncinci kwaye idibaniseke kakhulu yonke inkqubo.
Isicelo:
1. Inkqubo yonxibelelwano: Izithinteli ezilawulwa yiVoltha zingasetyenziselwa ukulungisa amandla esignali kwinkqubo yonxibelelwano, zifezekise ulawulo lwesignali kunye nolawulo ngexesha lokudluliselwa kwedatha kunye nokwamkelwa kwayo.
2. Ulawulo lwesandi: Izithinteli zesandi ezilawulwa yiVolthi zingasebenza njengeyunithi yolawulo lwesandi kwinkqubo yesandi ukulawula ukuncitshiswa kwemiqondiso yesandi.
3. Ukulinganiswa kwezixhobo: Ii-attenuators ezilawulwa yi-voltage zingasetyenziswa njengenxalenye yolawulo ekulinganisweni kwezixhobo ukulawula ngokuchanekileyo nokulungisa imiqondiso, ukufezekisa ukuchaneka kunye nozinzo lwezixhobo.
4. Ukucubungula isandi: Izithinteli ezilawulwa yiVoltha zingasetyenziswa ekucubungulweni kwesandi, ezinje ngezinto ezidibanisa isandi, izinto ezidityanisayo, izinto ezicinezelayo, njl.njl.
I-Qualwaveibonelela ngeebhendi ezibanzi kunye nee-attenuators ezilawulwa yi-voltage range ephezulu kwi-frequency ukuya kuthi ga kwi-90GHz. Ii-attenuators zethu ezilawulwa yi-voltage zisetyenziswa kakhulu kwiindawo ezininzi.
