Bloklash pastga aylantiruvchi (LNB)

Aloqa tizimlarida signal uzatishni osonlashtirish va kanalni qayta ishlatishga erishish uchun uzatiladigan signallarning chastotasi juda yuqori, shuning uchun signallarning chastota konvertatsiyasi aloqa tizimini tadqiq qilishning muhim jihati hisoblanadi. Chastotani konvertatsiya qilishdan oldingi va keyingi holatga ko'ra, uni pastga aylantirish (chastotani kamaytirish) va yuqoriga aylantirish (chastotani oshirish) ga bo'linishi mumkin.
Qabul qilgichda, agar aralashtirishdan keyin olingan oraliq chastotali signal asl signaldan past bo'lsa, unda bu aralashtirish usuli blokli pastga aylantiruvchilar (LNB) deb ataladi.
Blokni pastga o'tkazgichlarning usuli qabul qilingan signalni mahalliy osilator tomonidan ishlab chiqarilgan mahalliy osilator signali bilan ko'paytirish va keyin past chastotali filtr orqali aylantirilgan signalni olishdir. Ikkita ko'paytirilgan signalni haqiqiy yoki murakkab vakillik orqali haqiqiy aralashtirish va murakkab aralashtirishga bo'lish mumkin.
Blokni pastga aylantiruvchilarning maqsadi signalning tashuvchisi chastotasini kamaytirish yoki asosiy tarmoqli signalni olish uchun tashuvchi chastotasini to'g'ridan-to'g'ri olib tashlashdir. Oddiy sxemasi va arzonligi tufayli pastga aylantirish usuli past ishlash talablari bo'lgan fuqarolik texnikasi va harbiy texnikada keng qo'llaniladi.

Ilova:

1. Sun'iy yo'ldosh televideniesi: LNBlar sun'iy yo'ldosh televideniesini qabul qilish tizimlarining asosiy komponentlari hisoblanadi. Ular sun'iy yo'ldosh antennasining (paraboloid yoki idishning) markazlashtirilgan nuqtasiga o'rnatiladi, sun'iy yo'ldosh tomonidan uzatiladigan televizor signalini oladi va uni qabul qiluvchi tomonidan qayta ishlanishi mumkin bo'lgan oraliq chastotali signalga aylantiradi.
2. Sun'iy yo'ldosh Internet: Sun'iy yo'ldosh Internet tizimlarida sun'iy yo'ldoshlardan uzatiladigan Internet ma'lumotlarini qabul qilish uchun kuchaytirgichlardan foydalaniladi. Foydalanuvchi uskunasi LNB orqali ma'lumotlarni qabul qiladi va modem orqali ularni dekodlaydi va qayta ishlaydi.
3. Sun'iy yo'ldosh aloqalari: RF kuchaytirgichlari turli sun'iy yo'ldosh aloqa tizimlarida, jumladan, sun'iy yo'ldosh telefonlari, sun'iy yo'ldosh eshittirishlari, sun'iy yo'ldosh ma'lumotlarini uzatish va boshqalarda keng qo'llaniladi. Ular sun'iy yo'ldoshlardan uzatiladigan har xil turdagi aloqa signallarini qabul qilish va qayta ishlashga yordam beradi.
4. Yerni kuzatish va masofadan zondlash: Yerni kuzatish va masofadan zondlashning ba'zi ilovalarida sun'iy yo'ldoshlardan uzatiladigan masofaviy zondlash ma'lumotlarini qabul qilish uchun mikroto'lqinli kuchaytirgichlar qo'llaniladi. Ushbu ma'lumotlardan meteorologik monitoring, atrof-muhit monitoringi, ofat haqida ogohlantirish va boshqa sohalarda foydalanish mumkin.
Xulosa qilib aytganda, LNBlar zamonaviy sun'iy yo'ldosh aloqa tizimlarida muhim rol o'ynaydi va televidenie eshittirishlari, Internetga kirish, ma'lumotlar kommunikatsiyalari va turli professional sohalarda keng qo'llaniladi.

QualwaveS~Ka-bandidagi shovqin harorati 45~240K bo'lgan har xil turdagi Blokni tushirish konvertorlarini (LNB) etkazib beradi. Mijozlarning ehtiyojlarini qondirish uchun har xil turdagi tugatishlar.
