RF keng polosali EMC past shovqin kuchaytirgichlari
Kam shovqin kuchaytirgich - bu juda past shovqin ko'rsatkichiga ega kuchaytirgich bo'lib, zaif signallarni kuchaytirish va kuchaytirgich tomonidan kiritilgan shovqinni minimallashtirish uchun kontaktlarning zanglashiga olib keladi.
Odatda turli xil radio qabul qiluvchilarning yuqori chastotali yoki oraliq chastotali preamplifikatori va yuqori sezgirlikdagi elektron detektor uskunalarini kuchaytirish davri sifatida ishlatiladi.Yaxshi past shovqinli kuchaytirgich signalni kuchaytirishi va iloji boricha past shovqin va buzilishlarni keltirib chiqarishi kerak.
Past shovqinli kuchaytirgichlarning asosiy xususiyatlari va qo'llanilishi quyidagilar:
1. Daromadni kuchaytirish: LNA zaif kirish signallarini keyingi sxema yoki tizimni qayta ishlash uchun etarli darajaga oshirishi mumkin.Simsiz aloqada qabul qilingan signal ko'pincha juda zaif va LNA ning kuchaytirish effekti orqali signalni keyingi qayta ishlash va demodulyatsiyani ta'minlash uchun ishonchli darajaga oshirish mumkin.
2. Tizim shovqinini kamaytiring: LNA signalni kuchaytirganda qo'shimcha shovqinni minimallashtirishga intiladi.Shovqin simsiz aloqa tizimlarining ishlashi uchun juda muhim, chunki u signallarni maskalashi va tizimning signal-shovqin nisbatini kamaytirishi mumkin.Kam shovqin kuchaytirgichi optimallashtirilgan sxema dizayni va past shovqinli materiallardan foydalanish orqali shovqin ko'rsatkichini minimallashtirish orqali tizim shovqinini kamaytiradi.
3. Tizimning dinamik diapazonini yaxshilash: LNA ning yana bir vazifasi tizimning dinamik diapazonini kengaytirishdir.Dinamik diapazon tizimning kuchli va zaif signallarni bir vaqtning o'zida boshqarish qobiliyatini anglatadi.Kam shovqin kuchaytirgichlar kuchliroq signallar tufayli ortiqcha yuk yoki buzilishlarsiz zaifroq signallarni boshqarishi mumkin.Bu tizimga signal kuchining katta farqlari bo'lgan muhitda samarali ishlashiga imkon beradi.
LNA ning asosiy qo'llanilishi sohalari simsiz aloqa, tibbiy asbob-uskunalar, o'lchash asboblari, radar, sun'iy yo'ldosh aloqasi va boshqalar.
QualwaveDC dan 110 gigagertsgacha past shovqin kuchaytirgichlarini etkazib beradi va shovqin ko'rsatkichi 0,7 dB gacha bo'lishi mumkin.Minimal daromad 10dB va maksimal kirish VSWR 3,5:1.RF, mikroto'lqinli pech va millimetrli to'lqinli kuchaytirgich komponentlariga bo'lgan barcha ehtiyojlaringizni qondirish uchun turli xil past shovqin kuchaytirgich tizimlarini taklif etamiz.
