    Blok Downconverters (LNBs)

    Ing sistem komunikasi, kanggo nggampangake transmisi sinyal lan entuk panggunaan maneh saluran, frekuensi sinyal sing ditularake dhuwur banget, mula konversi frekuensi sinyal minangka aspek penting ing riset sistem komunikasi. Miturut kahanan sadurunge lan sawise konversi frekuensi, bisa dipérang dadi mudhun konversi (frekuensi abang) lan munggah konversi (frekuensi mundhak).
    Ing panrima, yen sinyal frekuensi penengah sing dipikolehi sawise nyampur luwih murah tinimbang sinyal asli, mula metode pencampuran iki diarani block downconverters (LNBs).
    Cara pamblokiran downconverters kanggo Multiply sinyal ditampa karo sinyal osilator lokal kui dening osilator lokal, lan banjur entuk sinyal diowahi liwat Filter low-pass. Loro sinyal sing dikalikan bisa dipérang dadi campuran nyata lan campuran kompleks liwat perwakilan nyata utawa kompleks.
    Tujuan downconverters blok yaiku nyuda frekuensi operator sinyal utawa langsung mbusak frekuensi operator kanggo entuk sinyal baseband. Amarga sirkuit sing gampang lan biaya sing murah, metode konversi mudhun digunakake ing peralatan sipil lan peralatan militer kanthi syarat kinerja sing sithik.

    Aplikasi:

    1. TV Satelit: LNB minangka komponen utama ing sistem resepsi TV satelit. Padha dipasang ing titik fokus antena satelit (paraboloid utawa sajian), nampa sinyal TV sing dikirim dening satelit, lan ngowahi dadi sinyal frekuensi penengah sing bisa diproses dening panrima.
    2. Internet Satelit: Ing sistem Internet satelit, LNB digunakake kanggo nampa data Internet sing dikirim saka satelit. Peralatan pangguna nampa data liwat LNB lan decode lan proses liwat modem.
    3. Komunikasi Satelit: LNB akeh digunakake ing macem-macem sistem komunikasi satelit, kalebu telpon satelit, siaran satelit, transmisi data satelit, lan sapiturute. Padha mbantu nampa lan ngolah macem-macem jinis sinyal komunikasi sing dikirim saka satelit.
    4. Observasi Bumi lan Remote Sensing: Ing sawetara aplikasi Observasi Bumi lan remote sensing, LNB digunakake kanggo nampa data sensing remot sing dikirim saka satelit. Data kasebut bisa digunakake ing pemantauan meteorologi, pemantauan lingkungan, peringatan bencana lan lapangan liyane.
    Ringkesan, LNB nduweni peran penting ing sistem komunikasi satelit modern lan akeh digunakake ing siaran televisi, akses Internet, komunikasi data lan macem-macem lapangan profesional.

    Qualwavenyedhiyakake macem-macem jinis Block Downconverters (LNBs) ing S~Ka-Band, kanthi suhu swara 45~240K. Terminasi kanthi macem-macem jinis kanggo nyukupi kabutuhan pelanggan.
