Zuia Vigeuzi vya chini (LNBs)

Katika mifumo ya mawasiliano, ili kuwezesha uwasilishaji wa mawimbi na kufikia utumiaji tena wa chaneli, mzunguko wa mawimbi yanayopitishwa ni wa juu sana, hivyo ubadilishaji wa mawimbi ya ishara ni kipengele muhimu cha utafiti wa mfumo wa mawasiliano. Kulingana na hali kabla na baada ya ubadilishaji wa masafa, inaweza kugawanywa katika ubadilishaji wa chini (kupunguza masafa) na ubadilishaji wa juu (ongezeko la masafa).
Katika mpokeaji, ikiwa ishara ya mzunguko wa kati iliyopatikana baada ya kuchanganya ni ya chini kuliko ishara ya awali, basi njia hii ya kuchanganya inaitwa block downconverters (LNBs).
Njia ya kuzuia downconverters ni kuzidisha ishara iliyopokelewa na ishara ya oscillator ya ndani inayozalishwa na oscillator ya ndani, na kisha kupata ishara iliyobadilishwa kupitia chujio cha chini. Ishara mbili zilizozidishwa zinaweza kugawanywa katika kuchanganya halisi na kuchanganya ngumu kupitia uwakilishi halisi au tata.
Madhumuni ya vibadilishaji vibadilishaji vya kuzuia ni kupunguza mzunguko wa mtoa huduma wa mawimbi au kuondoa moja kwa moja masafa ya mtoa huduma ili kupata mawimbi ya bendi ya msingi. Kwa sababu ya mzunguko wake rahisi na gharama ya chini, njia ya ubadilishaji wa chini hutumiwa sana katika vifaa vya kiraia na vifaa vya kijeshi na mahitaji ya chini ya utendaji.

Maombi:

1. Televisheni ya Satelaiti: LNB ni sehemu muhimu katika mifumo ya kupokea TV ya setilaiti. Zimewekwa kwenye kitovu cha antena ya satelaiti (paraboloid au sahani), hupokea mawimbi ya TV inayopitishwa na setilaiti, na kuibadilisha kuwa mawimbi ya masafa ya kati ambayo yanaweza kuchakatwa na mpokeaji.
2. Mtandao wa Satelaiti: Katika mifumo ya mtandao ya satelaiti, vikuza sauti hutumika kupokea data ya mtandao inayopitishwa kutoka kwa satelaiti. Kifaa cha mtumiaji hupokea data kupitia LNB na kuichambua na kuichakata kupitia modemu.
3. Mawasiliano ya Satelaiti: Vikuza sauti vya RF vinatumika sana katika mifumo mbalimbali ya mawasiliano ya satelaiti, ikiwa ni pamoja na simu za satelaiti, matangazo ya satelaiti, upitishaji wa data za satelaiti, n.k. Husaidia kupokea na kuchakata aina mbalimbali za ishara za mawasiliano zinazopitishwa kutoka kwa satelaiti.
4. Uchunguzi wa Dunia na Kuhisi kwa Mbali: Katika baadhi ya programu za uchunguzi wa Dunia na kutambua kwa mbali, vikuza vya microwave hutumiwa kupokea data ya kutambua kwa mbali inayopitishwa kutoka kwa satelaiti. Data hizi zinaweza kutumika katika ufuatiliaji wa hali ya hewa, ufuatiliaji wa mazingira, onyo la maafa na nyanja zingine.
Kwa muhtasari, LNB zina jukumu muhimu katika mifumo ya kisasa ya mawasiliano ya satelaiti na hutumiwa sana katika utangazaji wa televisheni, ufikiaji wa mtandao, mawasiliano ya data na nyanja mbalimbali za kitaaluma.

Qualwavehutoa aina mbalimbali za Block Downconverters (LNBs) katika S~Ka-Band, yenye halijoto ya kelele ya 45~240K. Kusimamishwa kwa aina tofauti ili kukidhi mahitaji ya wateja.
