Abahindura ba “Block Downconverters” (LNBs)

Muri sisitemu z'itumanaho, kugira ngo horoherezwe kohereza ibimenyetso no kongera gukoresha imiyoboro, inshuro z'ibimenyetso byoherejwe ziba nyinshi cyane, bityo guhindura inshuro z'ibimenyetso ni ingenzi mu bushakashatsi ku buryo bw'itumanaho. Dukurikije uko ibintu bimeze mbere na nyuma yo guhindura inshuro, bishobora kugabanywamo ibice bibiri: guhindura hasi (kugabanya inshuro) no kongera (kongera inshuro).
Mu mashini ikoresha ikoranabuhanga, niba ikimenyetso cy’impinduka hagati cyabonetse nyuma yo kuvanga kiri hasi ugereranije n’icyari cyarabonetse mbere, ubu buryo bwo kuvanga bwitwa block downconverters (LNBs).
Uburyo bwa "block downconverters" ni ukugwiza ikimenyetso cyakiriwe ukoresheje ikimenyetso cya "local oscillator" cyakozwe na "local oscillator", hanyuma ukabona ikimenyetso cyahinduwe unyuze muri "low-pass filter". Ibimenyetso bibiri byakubye inshuro ebyiri bishobora kugabanywamo kuvanga nyako n'kuvanga gukomeye binyuze mu kwerekana nyako cyangwa gukomeye.
Intego ya "block downconverters" ni ukugabanya inshuro zitwara ikimenyetso cyangwa gukuraho inshuro zitwara ikimenyetso kugira ngo ubone ikimenyetso cya baseband. Bitewe n'uko ari cyo cyoroshye kandi gihendutse, uburyo bwo guhindura down bukoreshwa cyane mu bikoresho bya gisivili n'ibikoresho bya gisirikare bifite ubushobozi buke bwo gukora.

Porogaramu:

1. Televiziyo ya Satelite: LNB ni ibice by'ingenzi muri sisitemu yo kwakira televiziyo ya satelite. Zishyirwa ku gice cy'ingenzi cya antene ya satelite (paraboloid cyangwa dish), zakira ikimenyetso cya televiziyo cyoherezwa na satelite, hanyuma zikagihindura ikimenyetso cy'intera gishobora gutunganywa na receiver.
2. Interineti ya Satelite: Muri sisitemu za interineti ya satelite, amplifiers zikoreshwa mu kwakira amakuru ya interineti yoherezwa kuri satelite. Ibikoresho by'umukoresha byakira amakuru binyuze muri LNB bikayasesengura kandi bigatunganywa binyuze muri modem.
3. Itumanaho rya Satelite: Amplifier za RF zikoreshwa cyane muri sisitemu zitandukanye z'itumanaho rya satelite, harimo telefoni za satelite, ibiganiro bya satelite, kohereza amakuru ya satelite, nibindi. Zifasha kwakira no gutunganya ubwoko butandukanye bw'ibimenyetso by'itumanaho byoherezwa bivuye kuri satelite.
4. Kwitegereza Isi no Gupima Ibidukikije: Muri bimwe mu bikorwa byo kwitegereza Isi no Gupima Ibidukikije, amplifiers za mikoroonde zikoreshwa mu kwakira amakuru yo kwitegereza Ibidukikije yoherejwe n'ibyogajuru. Aya makuru ashobora gukoreshwa mu kugenzura ikirere, gukurikirana ibidukikije, gutanga amakuru ku ibiza n'ibindi.
Muri make, LNB zigira uruhare runini muri sisitemu zigezweho z'itumanaho rya satelite kandi zikoreshwa cyane mu gusakaza televiziyo, gukoresha interineti, itumanaho ry'amakuru n'izindi nzego zitandukanye z'umwuga.

QualwaveItanga ubwoko butandukanye bwa Block Downconverters (LNBs) muri S~Ka-Band, ifite ubushyuhe bw'urusaku rwa 45~240K. Imiterere itandukanye kugira ngo ihuze n'ibyo abakiriya bakeneye.
