Muri sisitemu yo gutumanaho, kugirango byorohereze ibyapa byoherejwe no kugera ku miyoboro, inshuro zibimenyetso byoherejwe ni ndende cyane, bityo ihinduka ry'ibimenyetso ni ikintu cyingenzi cyubushakashatsi bwa sisitemu yitumanaho. Ukurikije uko ibintu bimeze mbere na nyuma yo guhinduka inshuro nyinshi, birashobora kugabanywamo guhinduka (kugabanuka kwimibanyi) no hejuru (kwiyongera kwose).
Mubyakira, niba ibimenyetso byinshi byimigati byabonetse nyuma yo kuvanga biri munsi yikimenyetso cyumwimerere, noneho uku buryo bwo kuvanga byitwa guhagarika (LNB).
Uburyo bwo guhagarika ibicucu ni ukugwiza ibimenyetso byakiriwe hamwe nisonga rya oscillator yaho ryakozwe na oscillator yaho, hanyuma ukabona ibimenyetso byahinduwe binyuze muyunguruzi. Ibimenyetso bibiri bigwizwa birashobora kugabanywamo kuvanga nyabyo no kugoreka binyuze mu guhagararirwa cyangwa bigoye.
Intego yo guhagarika ibinure ni ukugabanya inshuro zitwara ibimenyetso cyangwa ukureho inzira yimodoka yo kubona ibimenyetso bya baseband. Kubera umuzunguruko woroshye kandi ikiguzi gito, uburyo bwo guhindura hasi bukoreshwa cyane mubikoresho bya gisivili nibikoresho bya gisirikare nibisabwa mubiri.

Gusaba:

1. TV ya Satellite: LNBS nibigize ibyingenzi muri sisitemu ya Satelite Kwakira TV. Bashyizwe ahabigenewe annten ya antenne (paraboloid cyangwa ibiryo), bakira ibimenyetso bya televiziyo byatanzwe na satelite, hanyuma uyihindure ikimenyetso cyimikorere kidakoreshwa nuwakira.
2. Interineti ya Satelite: Muri sisitemu ya enterineti ya satelite, amplifiers ikoreshwa kugirango yakire amakuru ya interineti yoherejwe muri satelite. Ibikoresho byumukoresha byakira amakuru binyuze muri LNB na DECODE KANDI Bitunganya Binyuze muri Modem.
3. Itumanaho rya Satelite: Amplifiers RF ikoreshwa cyane muri sisitemu zitandukanye za satelite, harimo na terefone ya satelite, ibiganiro bya satelite, ibiganiro bya satelite byanduza kandi bigatuma habaho ibintu bitandukanye by'ibimenyetso byoherejwe bitangwa na satelite.
4. Indorerezi ku isi no kwiyumvisha kure: Mubyifuzo bimwe na bimwe byo kwitegereza kwisi no kwitegereza kure, amplifiers ya Microwave ikoreshwa muguhabwa amakuru yunvikana ya kure yoherejwe muri satelite. Aya makuru arashobora gukoreshwa mubugenzuzi bwikirere, gukurikirana ibidukikije, kuburira ibiza nibindi bibanza.
Muri make, LNB yagize uruhare runini muri sisitemu yitumanaho ya none kandi ikoreshwa cyane muri tereviziyo, uburyo bwa interineti, Itumanaho rya Data hamwe nimirima itandukanye yabigize umwuga.

UmwandaGutanga Ubwoko butandukanye bwo guhagarika (LNB) muri S ~ ka-band, hamwe nubushyuhe bwurusaku bwa 45 ~ 240k. Gutangariza kwubwoko butandukanye kugirango twuzuze ibikenewe byabakiriya.
