Yn kommunikaasjesystemen is de frekwinsje fan útstjoerde sinjalen heul heech, om sinjaaloerdracht te fasilitearjen en wergebrûk fan kanaal te berikken, sadat frekwinsjekonverzje fan sinjalen in wichtich aspekt is fan ûndersyk nei kommunikaasjesysteem. Neffens de situaasje foar en nei frekwinsjekonverzje, kin it wurde ferdield yn downkonverzje (frekwinsjereduksje) en omheechkonverzje (frekwinsjeferheging).
Yn 'e ûntfanger, as it tuskenfrekwinsjesinjaal krigen nei it mingen leger is dan it orizjinele sinjaal, dan wurdt dizze mingmetoade block downconverters (LNB's) neamd.
De metoade fan block downconverters is om it ûntfongen sinjaal te fermannichfâldigjen mei it lokale oscillator-sinjaal generearre troch de lokale oscillator, en dan it omboude sinjaal te krijen fia in leechpassfilter. Twa fermannichfâldige sinjalen kinne wurde ferdield yn echte mingen en komplekse mingen troch echte of komplekse fertsjintwurdiging.
It doel fan blok downconverters is om de dragerfrekwinsje fan it sinjaal te ferminderjen of de dragerfrekwinsje direkt te ferwiderjen om it basisbânsinjaal te krijen. Troch syn ienfâldige sirkwy en lege kosten, wurdt de metoade foar delkonverzje in soad brûkt yn sivile apparatuer en militêre apparatuer mei lege prestaasjeseasken.
1. Satellite TV: LNBs binne wichtige komponinten yn satellyt TV ûntfangst systemen. Se wurde ynstalleare op it fokuspunt fan in satellytantenne (paraboloïde as skûtel), ûntfange it tv-sinjaal dat troch de satellyt wurdt oerbrocht, en konvertearje it yn in sinjaal foar tuskenfrekwinsje dat kin wurde ferwurke troch de ûntfanger.
2. Satellytynternet: Yn satellytynternetsystemen wurde LNB's brûkt om ynternetgegevens te ûntfangen dy't oerdroegen wurde fan satelliten. De brûkersapparatuer ûntfangt de gegevens fia de LNB en dekodearret en ferwurket it fia it modem.
3. Satellite Communications: LNBs wurde in soad brûkt yn ferskate satellyt kommunikaasje systemen, ynklusyf satellyt telefoans, satellyt útstjoerings, satellyt gegevens oerdracht, ensfh Se helpe ûntfange en ferwurkjen ferskate soarten kommunikaasje sinjalen oerdroegen fan satelliten.
4. Earth Observation en Remote Sensing: Yn guon Earth observation en remote sensing applikaasjes, LNBs wurde brûkt om te ûntfangen remote sensing gegevens oerdroegen fan satelliten. Dizze gegevens kinne brûkt wurde yn meteorologyske monitoring, miljeumonitoring, disaster warskôging en oare fjilden.
Gearfetsjend spylje LNB's in fitale rol yn moderne satellytkommunikaasjesystemen en wurde in protte brûkt yn televyzje-útstjoeringen, ynternettagong, datakommunikaasje en ferskate profesjonele fjilden.
Qualwaveleveret ferskate soarten Block Downconverters (LNB's) yn 'e S~Ka-Band, mei in lûdtemperatuer fan 45 ~ 240K. De beëinigingen mei ferskate soarten om te foldwaan oan 'e behoeften fan klanten.
