    Konverter Blok Down (LNB)

    Ing sistem komunikasi, kanggo nggampangake transmisi sinyal lan entuk panggunaan saluran maneh, frekuensi sinyal sing dikirim dhuwur banget, mula konversi frekuensi sinyal minangka aspek penting saka riset sistem komunikasi. Miturut kahanan sadurunge lan sawise konversi frekuensi, bisa dipérang dadi konversi mudhun (pengurangan frekuensi) lan konversi munggah (peningkatan frekuensi).
    Ing panrima, yèn sinyal frekuensi menengah sing dipikolehi sawisé pencampuran luwih endhek tinimbang sinyal asli, mula cara pencampuran iki diarani block downconverters (LNB).
    Carané nggunakaké block downconverter yaiku nggandakaké sinyal sing ditampa karo sinyal osilator lokal sing diasilaké déning osilator lokal, banjur éntuk sinyal sing dikonversi liwat filter low-pass. Rong sinyal sing digandakaké bisa dipérang dadi pencampuran nyata lan pencampuran kompleks liwat representasi nyata utawa kompleks.
    Tujuan saka block downconverter yaiku kanggo ngurangi frekuensi operator sinyal utawa langsung mbusak frekuensi operator kanggo entuk sinyal baseband. Amarga sirkuite sing prasaja lan biaya sing murah, metode down conversion digunakake sacara wiyar ing peralatan sipil lan peralatan militer kanthi syarat kinerja sing kurang.

    Aplikasi:

    1. TV Satelit: LNB minangka komponen kunci ing sistem panrima TV satelit. LNB dipasang ing titik fokus antena satelit (paraboloid utawa parabola), nampa sinyal TV sing dikirim dening satelit, lan ngowahi dadi sinyal frekuensi menengah sing bisa diproses dening panrima.
    2. Internet Satelit: Ing sistem Internet satelit, amplifier digunakake kanggo nampa data Internet sing dikirim saka satelit. Piranti pangguna nampa data liwat LNB lan dekode lan proses liwat modem.
    3. Komunikasi Satelit: Amplifier RF digunakake sacara wiyar ing macem-macem sistem komunikasi satelit, kalebu telpon satelit, siaran satelit, transmisi data satelit, lan liya-liyane. Amplifier iki mbantu nampa lan ngolah macem-macem jinis sinyal komunikasi sing dikirim saka satelit.
    4. Observasi Bumi lan Penginderaan Jauh: Ing sawetara aplikasi observasi Bumi lan penginderaan jauh, penguat gelombang mikro digunakake kanggo nampa data penginderaan jauh sing dikirim saka satelit. Data kasebut bisa digunakake ing pemantauan meteorologi, pemantauan lingkungan, peringatan bencana, lan bidang liyane.
    Ringkesane, LNB nduweni peran penting ing sistem komunikasi satelit modern lan digunakake sacara wiyar ing siaran televisi, akses internet, komunikasi data, lan maneka warna bidang profesional.

    Gelombang Kualnyediakake macem-macem jinis Block Downconverter (LNB) ing S~Ka-Band, kanthi suhu gangguan 45~240K. Terminasi kanthi jinis sing beda-beda kanggo nyukupi kabutuhan pelanggan.
