GWB104G Umuyoboro mugari LNB
Ibisobanuro ku bicuruzwa
GWB104G numuyoboro mugari LNB hamwe nibisohoka bibiri bya RF.Hamwe na 10.4GHz oscillator yaho, GWB104G ihindura ibimenyetso bya 10.7GHz ~ 12.75GHz Ku band ya 300MHz ~ 2350MHz.
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.
Ibindi biranga:
•Ibyambu bibiri bya RF, buri 300MHz ~ 2350MHz.
•Urusaku ruke.
•Kwiyubaka byoroshye.
•Gukoresha ingufu nke.
•Kurinda ikirere cyiza.
•Ibisobanuro byuzuye bya Ku-Band kuri Analog na HD Kwakira Digital.
