Ma Block Downconverters (LNBs)

Mu makina olumikizirana, kuti zithandize kutumiza zizindikiro ndikukwaniritsa kugwiritsidwanso ntchito kwa njira, kuchuluka kwa zizindikiro zotumizirana kumakhala kwakukulu kwambiri, kotero kusintha kwa zizindikiro pafupipafupi ndi gawo lofunikira pakufufuza kwa makina olumikizirana. Malinga ndi momwe zinthu zilili kale komanso pambuyo pa kusintha kwa pafupipafupi, zitha kugawidwa m'magulu awiri: kusintha kwa pansi (kuchepetsa pafupipafupi) ndi kusintha kwa mmwamba (kuwonjezeka kwa pafupipafupi).
Mu cholandirira, ngati chizindikiro cha ma frequency apakati chomwe chapezeka mutasakaniza chili chotsika kuposa chizindikiro choyambirira, ndiye kuti njira yosakaniza iyi imatchedwa block downconverters (LNBs).
Njira yogwiritsira ntchito ma block downconverter ndikuchulukitsa chizindikiro cholandiridwa ndi chizindikiro cha local oscillator chopangidwa ndi local oscillator, kenako kupeza chizindikiro chosinthidwa kudzera mu fyuluta yotsika. Zizindikiro ziwiri zochulukitsa zitha kugawidwa m'magulu awiri: kusakaniza kwenikweni ndi kusakaniza kovuta kudzera mu chiwonetsero chenicheni kapena chovuta.
Cholinga cha ma block downconverter ndikuchepetsa kuchuluka kwa chizindikiro cha carrier kapena kuchotsa mwachindunji kuchuluka kwa chizindikiro cha carrier kuti mupeze chizindikiro cha baseband. Chifukwa cha dera lake losavuta komanso mtengo wotsika, njira yosinthira pansi imagwiritsidwa ntchito kwambiri pazida za anthu wamba komanso zida zankhondo zomwe sizigwira ntchito bwino.

Ntchito:

1. TV ya Satellite: Ma LNB ndi zinthu zofunika kwambiri mu makina olandirira TV ya satelayiti. Amayikidwa pamalo ofunikira a antenna ya satelayiti (paraboloid kapena dish), amalandira chizindikiro cha TV chomwe chimatumizidwa ndi satelayiti, ndikuchisintha kukhala chizindikiro cha pafupipafupi chomwe chingakonzedwe ndi wolandila.
2. Intaneti ya Satellite: Mu makina a intaneti ya satellite, ma amplifiers amagwiritsidwa ntchito kulandira deta ya intaneti yotumizidwa kuchokera ku ma satellite. Zipangizo zogwiritsa ntchito zimalandira deta kudzera mu LNB ndikuyisintha ndikuigwiritsa ntchito kudzera mu modem.
3. Kulankhulana ndi Satellite: Ma amplifiers a RF amagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana zolumikizirana ndi satelite, kuphatikizapo mafoni a satelite, kuwulutsa kwa satelite, kutumiza deta ya satelite, ndi zina zotero. Amathandiza kulandira ndi kukonza mitundu yosiyanasiyana ya zizindikiro zolumikizirana zomwe zimatumizidwa kuchokera ku satelite.
4. Kuyang'anira Dziko ndi Kuzindikira Kutali: Mu ntchito zina zoyang'anira Dziko ndi kuzindikira kutali, ma amplifiers a microwave amagwiritsidwa ntchito kulandira deta yowunikira kutali yotumizidwa kuchokera ku ma satellite. Deta iyi ingagwiritsidwe ntchito poyang'anira nyengo, kuyang'anira zachilengedwe, kuchenjeza za masoka ndi madera ena.
Mwachidule, ma LNB amagwira ntchito yofunika kwambiri m'njira zamakono zolumikizirana ndi ma satellite ndipo amagwiritsidwa ntchito kwambiri pakuwulutsa pa wailesi yakanema, kugwiritsa ntchito intaneti, kulumikizana ndi deta komanso m'magawo osiyanasiyana aukadaulo.

Qualwaveimapereka mitundu yosiyanasiyana ya Block Downconverters (LNBs) mu S~Ka-Band, yokhala ndi kutentha kwa phokoso la 45~240K. Mapeto ake ndi amitundu yosiyanasiyana kuti akwaniritse zosowa za makasitomala.
