G1 LNB
Ibisobanuro ku bicuruzwa
G1 ikurikirana rusange LNB ifite kimwe cyangwa impanga cyangwa Quattro isohoka, buri cyambu cya RF gifite 950 ~ 2150MHz ibisohoka hamwe na 13V cyangwa 18V bihindura imbaraga za DC biva mubakira.
Urusaku ruke rwerekana amajwi (LNB) nigikoresho cyakira gishyirwa kumasahani ya satelite, ikusanya imiraba ya radio ivuye mu isahani ikayihindura ku kimenyetso cyoherezwa hakoreshejwe umugozi ku cyakira imbere mu nyubako.LNB nayo yitwa guhagarika urusaku ruke, guhindura urusaku ruke (LNC), cyangwa se urusaku ruke rwo hasi (LND).
LNB ni ihuriro ry urusaku ruke rwinshi, ivangavanga, oscillator yaho hamwe nintera yo hagati (IF).Ikora nka RF imbere yimpera yakira icyogajuru, yakira ibimenyetso bya microwave bivuye kuri satelite yakusanyirijwe hamwe nisahani, kuyongerera imbaraga, no kumanura ihagarikwa ryumurongo kugeza kumurongo wo hasi wa interineti hagati (IF).Uku kumanura kwemerera ibimenyetso gutwarwa kuri televiziyo yo mu nzu ikoresheje insinga ya coaxial ihendutse ugereranije;niba ikimenyetso cyagumye kumurongo wambere wa microwave byasaba umurongo uhenze kandi udasanzwe.
Ubusanzwe LNB ni agasanduku gato kahagaritswe kuri kimwe cyangwa byinshi bigufi, cyangwa kugaburira amaboko, imbere yerekana ibyokurya, aho byibanda (nubwo ibishushanyo mbonera bimwe bifite LNB hejuru cyangwa inyuma yicyuma).Ikimenyetso cya microwave kiva mu isahani gitoragurwa na feedhorn kuri LNB hanyuma igaburirwa igice cya waveguide.Ipine imwe cyangwa nyinshi zicyuma, cyangwa probe, zisohoka mumurongo wumurongo wiburyo ugana umurongo hanyuma ugakora nka antene, ugaburira ibimenyetso kubibaho byacapishijwe imbere mumasanduku ya LNB akingiwe kugirango bitunganyirizwe.Inshuro yo hasi NIBA ibyasohotse bisohoka bivuye kumurongo wa kabili ya coaxial ihuza.
