Blokk DownConverters (LNBs)

Fis-sistemi ta 'komunikazzjoni, sabiex tiffaċilita t-trasmissjoni tas-sinjali u tinkiseb użu mill-ġdid tal-kanali, il-frekwenza ta' sinjali trasmessi hija għolja ħafna, u għalhekk il-konverżjoni tal-frekwenza tas-sinjali hija aspett importanti tar-riċerka tas-sistema ta 'komunikazzjoni. Skond is-sitwazzjoni ta 'qabel u wara l-konverżjoni tal-frekwenza, din tista' tinqasam fi konverżjoni 'l isfel (tnaqqis tal-frekwenza) u konverżjoni UP (żieda fil-frekwenza).
Fir-riċevitur, jekk is-sinjal tal-frekwenza intermedja miksub wara t-taħlit huwa inqas mis-sinjal oriġinali, allura dan il-metodu ta 'taħlit jissejjaħ block downconverters (LNBs).

L-iskop tal-konvertituri tal-blokka huwa li tnaqqas il-frekwenza tat-trasportatur tas-sinjal jew tneħħi direttament il-frekwenza tat-trasportatur biex tinkiseb is-sinjal tal-faxxa tal-bażi. Minħabba ċ-ċirkwit sempliċi u l-prezz baxx tiegħu, il-metodu ta 'konverżjoni' l isfel huwa użat ħafna f'tagħmir ċivili u tagħmir militari b'rekwiżiti ta 'prestazzjoni baxxa.

Applikazzjoni:

1. Satellite TV: LNBs huma komponenti ewlenin fis-sistemi ta 'akkoljenza tat-TV bis-satellita. Huma installati fil-punt fokali ta 'antenna bis-satellita (paraboloid jew dixx), jirċievu s-sinjal tat-TV trasmess mis-satellita, u jibdluh f'sinjal ta' frekwenza intermedju li jista 'jiġi pproċessat mir-riċevitur.
2. Internet bis-satellita: Fis-sistemi tal-internet bis-satellita, l-amplifikaturi jintużaw biex jirċievu dejta tal-internet trażmessa mis-satelliti. It-tagħmir tal-utent jirċievi d-dejta permezz tal-LNB u jiddekodifikaha u jipproċessaha permezz tal-modem.

4. Osservazzjoni tad-dinja u telerilevament: F'xi applikazzjonijiet ta 'osservazzjoni u telerilevament, amplifikaturi tal-majkrowejv jintużaw biex jirċievu dejta ta' telerilevament trażmessa mis-satelliti. These data can be used in meteorological monitoring, environmental monitoring, disaster warning and other fields.
Fil-qosor, l-LNBs għandhom rwol vitali fis-sistemi moderni ta 'komunikazzjoni bis-satellita u jintużaw ħafna fix-xandir televiżiv, aċċess għall-internet, komunikazzjonijiet tad-dejta u diversi oqsma professjonali.

QualwaveJipprovdu diversi tipi ta 'konvertituri tal-blokka (LNBs) fil-band s ~ ka, b'temperatura tal-ħoss ta '45 ~ 240k. It-terminazzjonijiet mat-tip differenti biex jissodisfaw il-bżonnijiet tal-klijenti.
