Blokni pastga aylantiruvchi konvertorlar (LNB)

Aloqa tizimlarida signal uzatishni osonlashtirish va kanallardan qayta foydalanishga 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 konvertatsiya (chastotani kamaytirish) va yuqoriga konvertatsiya (chastotani oshirish) ga bo'lish mumkin.
Qabul qilgichda, agar aralashtirishdan keyin olingan oraliq chastotali signal asl signaldan pastroq bo'lsa, unda bu aralashtirish usuli blokli pastga o'zgartirgichlar (LNB) deb ataladi.
Blok pastga aylantirgichlar usuli qabul qilingan signalni mahalliy osilator tomonidan ishlab chiqarilgan mahalliy osilator signali bilan ko'paytirish va keyin o'zgartirilgan signalni past chastotali filtr orqali olishdan iborat. Ikkita ko'paytirilgan signalni haqiqiy yoki murakkab tasvirlash orqali haqiqiy aralashtirish va murakkab aralashtirishga bo'lish mumkin.
Blok pastga konvertorlarining maqsadi signalning tashuvchi chastotasini kamaytirish yoki bazaviy polosali signalni olish uchun tashuvchi chastotasini to'g'ridan-to'g'ri olib tashlashdir. Oddiy sxemasi va arzonligi tufayli pastga konvertatsiya qilish usuli fuqarolik uskunalari va past ishlash talablariga ega harbiy texnikada keng qo'llaniladi.

Ilova:

1. Sun'iy yo'ldosh televideniyesi: LNBlar sun'iy yo'ldosh televideniyesini qabul qilish tizimlarining asosiy komponentlari hisoblanadi. Ular sun'iy yo'ldosh antennasining (paraboloid yoki antenna) markazlashtirilgan nuqtasiga o'rnatiladi, sun'iy yo'ldosh tomonidan uzatiladigan televideniye signalini qabul qiladi va uni qabul qilgich tomonidan qayta ishlanishi mumkin bo'lgan oraliq chastotali signalga aylantiradi.
2. Sun'iy yo'ldosh interneti: Sun'iy yo'ldosh internet tizimlarida kuchaytirgichlar sun'iy yo'ldoshlardan uzatiladigan internet ma'lumotlarini qabul qilish uchun ishlatiladi. Foydalanuvchi uskunasi ma'lumotlarni LNB orqali qabul qiladi va uni modem orqali dekodlaydi va qayta ishlaydi.
3. Sun'iy yo'ldosh aloqasi: RF kuchaytirgichlari turli xil sun'iy yo'ldosh aloqa tizimlarida, jumladan, sun'iy yo'ldosh telefonlarida, sun'iy yo'ldosh eshittirishlarida, sun'iy yo'ldosh ma'lumotlarini uzatishda va boshqalarda keng qo'llaniladi. Ular sun'iy yo'ldoshlardan uzatiladigan turli xil aloqa signallarini qabul qilish va qayta ishlashga yordam beradi.
4. Yerni kuzatish va masofadan zondlash: Ba'zi Yerni kuzatish va masofadan zondlash ilovalarida mikroto'lqinli kuchaytirgichlar sun'iy yo'ldoshlardan uzatiladigan masofadan zondlash ma'lumotlarini qabul qilish uchun ishlatiladi. Ushbu ma'lumotlar meteorologik monitoring, atrof-muhit monitoringi, falokatlar haqida ogohlantirish va boshqa sohalarda qo'llanilishi mumkin.
Xulosa qilib aytganda, LNBlar zamonaviy sun'iy yo'ldosh aloqa tizimlarida muhim rol o'ynaydi va televizion eshittirish, internetga kirish, ma'lumotlar uzatish va turli professional sohalarda keng qo'llaniladi.

QualwaveS~Ka-diapazonida 45 ~ 240K shovqin haroratiga ega bo'lgan turli xil blokli pastga o'zgartirgichlarni (LNB) yetkazib beradi. Mijozlarning ehtiyojlarini qondirish uchun turli xil terminallar mavjud.
