    Block Downconverters (LNBs)

    M'machitidwe oyankhulana, kuti athe kupititsa patsogolo kufalitsa zizindikiro ndikukwaniritsa kugwiritsiranso ntchito njira, mafupipafupi a zizindikiro zopatsirana ndizokwera kwambiri, kotero kutembenuka kwafupipafupi kwa zizindikiro ndizofunikira kwambiri pa kafukufuku wa machitidwe olankhulana. Malingana ndi momwe zinalili musanayambe komanso pambuyo pa kutembenuka kwafupipafupi, imatha kugawidwa pansi (kuchepetsa mafupipafupi) ndi kutembenuka kwapamwamba (kuwonjezeka kwafupipafupi).
    Mu wolandila, ngati chizindikiro chapakati chapakati chomwe chimapezedwa pambuyo pa kusakaniza ndi chotsika kuposa chizindikiro choyambirira, ndiye kuti njira yosakanikiranayi imatchedwa block downconverters (LNBs).
    Njira ya block downconverters ndi kuchulukitsa chizindikiro cholandilidwa ndi chizindikiro cha oscillator chapafupi chomwe chimapangidwa ndi oscillator wamba, ndiyeno kupeza chizindikiro chosinthidwa kupyolera mu fyuluta yotsika. Zizindikiro ziwiri zochulukitsa zikhoza kugawidwa kukhala kusakaniza kwenikweni ndi kusakaniza kovutirapo kupyolera mu kuyimira kwenikweni kapena kovuta.
    Cholinga cha block downconverters ndikuchepetsa kuchuluka kwa chonyamulira cha siginecha kapena kuchotsa mwachindunji ma frequency onyamula kuti mupeze chizindikiro cha baseband. Chifukwa cha dera lake losavuta komanso lotsika mtengo, njira yosinthira pansi imagwiritsidwa ntchito kwambiri pazida zankhondo ndi zida zankhondo zokhala ndi zofunikira zochepa.

    Ntchito:

    1. Satellite TV: Ma LNB ndi zigawo zazikulu mu makina olandirira ma TV a satana. Amayikidwa pakatikati pa mlongoti wa satana (paraboloid kapena dish), kulandira chizindikiro cha TV chomwe chimaperekedwa ndi satellite, ndikuchisintha kukhala chizindikiro chapakati chomwe chimatha kusinthidwa ndi wolandira.
    2. Paintaneti ya Satellite: M'makina apaintaneti a satellite, ma LNB amagwiritsidwa ntchito polandila data ya pa intaneti kuchokera ku masetilaiti. Zida zogwiritsira ntchito zimalandira deta kudzera mu LNB ndikuzilemba ndikuzikonza kudzera mu modemu.
    3. Kuyankhulana kwa Satellite: Ma LNB amagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana zoyankhulirana za satellite, kuphatikizapo mafoni a satana, mauthenga a satana, kutumiza deta ya satellite, ndi zina zotero. Amathandizira kulandira ndi kukonza mitundu yosiyanasiyana ya zizindikiro zoyankhulirana zotumizidwa kuchokera ku satellites.
    4. Kuyang'ana Padziko Lapansi ndi Kumva Kutali: Muzinthu zina zapadziko lapansi ndi zowonera patali, ma LNB amagwiritsidwa ntchito kulandira chidziwitso chakutali chotumizidwa kuchokera kumasetilaiti. Izi zitha kugwiritsidwa ntchito powunika zanyengo, kuyang'anira zachilengedwe, kuchenjeza za tsoka ndi zina.
    Mwachidule, ma LNB amatenga gawo lofunikira kwambiri pamakina amakono olankhulirana pa satellite ndipo amagwiritsidwa ntchito kwambiri pakuwulutsa pawayilesi pawailesi yakanema, kugwiritsa ntchito intaneti, kulumikizana ndi data komanso magawo osiyanasiyana aukadaulo.

    Qualwaveamapereka mitundu yosiyanasiyana ya Block Downconverters (LNBs) mu S~Ka-Band, ndi kutentha kwa phokoso kwa 45~240K. The terminationswith zosiyanasiyana mtundu kukwaniritsa zosowa za makasitomala.
