    Blok Downconverters (LNBs)

    Dina sistem komunikasi, pikeun ngagampangkeun pangiriman sinyal sareng ngahontal pamakean deui saluran, frekuensi sinyal anu dikirimkeun pisan tinggi, janten konvérsi frekuensi sinyal mangrupikeun aspék penting dina panalungtikan sistem komunikasi. Numutkeun kaayaan saméméh jeung sanggeus konversi frékuénsi, éta bisa dibagi kana handap konversi (réduksi frékuénsi) jeung up konversi (frékuénsi kanaékan).
    Dina panarima, lamun sinyal frékuénsi panengah diala sanggeus pergaulan leuwih handap tina sinyal aslina, mangka métode mixing ieu disebut block downconverters (LNBs).
    Metoda block downconverters nyaéta ngalikeun sinyal narima jeung sinyal osilator lokal dihasilkeun ku osilator lokal, lajeng ménta sinyal dirobah ngaliwatan filter low-pass. Dua sinyal dikalikeun bisa dibagi kana pergaulan nyata jeung pergaulan kompléks ngaliwatan ngagambarkeun nyata atawa kompléks.
    Tujuan block downconverters nyaéta pikeun ngurangan frékuénsi pamawa sinyal atawa langsung nyabut frékuénsi pamawa pikeun ménta sinyal baseband. Alatan sirkuit basajan sarta béaya rendah, métode konvérsi handap loba dipaké dina parabot sipil jeung alat-alat militer jeung syarat kinerja low.

    Aplikasi:

    1. TV satelit: LNB mangrupakeun komponén konci dina sistem panarimaan TV satelit. Éta dipasang dina titik fokus anteneu satelit (paraboloid atanapi piringan), nampi sinyal TV anu dikirimkeun ku satelit, sareng ngarobih kana sinyal frekuensi panengah anu tiasa diolah ku panarima.
    2. Internet Satelit: Dina sistem Internet satelit, LNB dipaké pikeun nampa data Internét dikirimkeun ti satelit. Parabot pamaké narima data ngaliwatan LNB jeung decodes sarta prosés ngaliwatan modem nu.
    3. Komunikasi Satelit: LNB loba dipaké dina sagala rupa sistem komunikasi satelit, kaasup telepon satelit, siaran satelit, transmisi data satelit, jeung sajabana Éta mantuan narima jeung ngolah rupa-rupa sinyal komunikasi dikirimkeun ti satelit.
    4. Observasi Bumi sareng Remote Sensing: Dina sababaraha aplikasi observasi Bumi sareng remote sensing, LNB dianggo pikeun nampi data sensing jauh anu dikirimkeun tina satelit. Data ieu tiasa dianggo dina ngawaskeun météorologi, ngawaskeun lingkungan, peringatan bencana sareng widang sanésna.
    Kasimpulanana, LNB maénkeun peran penting dina sistem komunikasi satelit modern sareng seueur dianggo dina siaran televisi, aksés Internét, komunikasi data sareng sagala rupa widang profésional.

    Qualwavesuplai rupa-rupa Block Downconverters (LNBs) dina S~Ka-Band, kalawan suhu noise 45~240K. The terminationswith tipe béda pikeun minuhan kabutuhan konsumén.
