Hagarika Downconverters (LNBs)

Muri sisitemu yitumanaho, kugirango byoroherezwe kohereza ibimenyetso no kugera kumuyoboro wongeye gukoreshwa, inshuro zerekana ibimenyetso byoherejwe ni byinshi cyane, bityo guhinduranya ibimenyetso inshuro ni ikintu cyingenzi cyubushakashatsi bwa sisitemu yitumanaho. Ukurikije uko ibintu bimeze mbere na nyuma yo guhinduranya inshuro, birashobora kugabanywa guhinduka hasi (kugabanya inshuro) no kuzamuka (kwiyongera inshuro).
Mubakira, niba ibimenyetso byigihe gito byabonetse nyuma yo kuvanga biri munsi yikimenyetso cyambere, ubwo buryo bwo kuvanga bwitwa block downconverters (LNBs).
Uburyo bwo guhagarika kumanura ibintu ni ukugwiza ibimenyetso byakiriwe hamwe nibimenyetso bya oscillator byaho byakozwe na oscillator yaho, hanyuma ukabona ibimenyetso byahinduwe binyuze mumashanyarazi make. Ibimenyetso bibiri byikubye birashobora kugabanwa kuvanga nyabyo no kuvanga bigoye binyuze mubyukuri cyangwa bigoye.
Intego yo guhagarika ibimanuka ni ukugabanya inshuro zitwara ibimenyetso cyangwa gukuraho byimazeyo ubwikorezi kugirango ubone ikimenyetso cya baseband. Bitewe numuzunguruko woroshye hamwe nigiciro gito, uburyo bwo guhindura ibintu bukoreshwa cyane mubikoresho bya gisivili nibikoresho bya gisirikare bifite ubushobozi buke.

Gusaba:

1. TV ya Satelite: LNBs nibintu byingenzi muri sisitemu yo kwakira televiziyo. Bashyizwe ahantu hibandwaho na antenne ya satelite (paraboloide cyangwa isahani), bakira ibimenyetso bya tereviziyo yoherejwe na satelite, hanyuma bakabihindura ikimenyetso giciriritse gishobora gutunganywa nuwakiriye.
2. Internet ya Satelite: Muri sisitemu ya interineti ya satelite, LNBs zikoreshwa mu kwakira amakuru ya interineti yoherejwe na satelite. Ibikoresho byabakoresha byakira amakuru binyuze muri LNB na decode kandi ikabitunganya binyuze muri modem.
3.
4. Aya makuru arashobora gukoreshwa mugukurikirana ikirere, kugenzura ibidukikije, kuburira ibiza nizindi nzego.
Muri make, LNBs igira uruhare runini muri sisitemu yitumanaho rya kijyambere kandi ikoreshwa cyane mugutangaza kuri tereviziyo, kugera kuri interineti, itumanaho ryamakuru ndetse no mubice bitandukanye byumwuga.

Qualwaveitanga ubwoko butandukanye bwa Block Downconverters (LNBs) muri S ~ Ka-Band, hamwe nubushyuhe bwurusaku rwa 45 ~ 240K. Kurangiza hamwe nubwoko butandukanye kugirango uhuze ibyo abakiriya bakeneye.
