    Blòk Downconverters (LNB)

    Nan sistèm kominikasyon yo, yo nan lòd yo fasilite transmisyon siyal ak reyalize chanèl reutilize, frekans nan siyal transmèt yo trè wo, kidonk konvèsyon frekans nan siyal se yon aspè enpòtan nan rechèch sistèm kominikasyon. Dapre sitiyasyon an anvan ak apre konvèsyon frekans, li ka divize an konvèsyon desann (rediksyon frekans) ak konvèsyon moute (ogmantasyon frekans).
    Nan reseptè a, si siyal frekans entèmedyè a jwenn apre melanje pi ba pase siyal orijinal la, Lè sa a, metòd sa a melanje yo rele blòk downconverters (LNBs).
    Metòd la nan blòk downconverters se miltipliye siyal la resevwa ak siyal la osilateur lokal ki te pwodwi pa osilator lokal la, ak Lè sa a, jwenn siyal la konvèti atravè yon filtè ki ba-pase. De siyal miltipliye ka divize an melanje reyèl ak melanje konplèks atravè reprezantasyon reyèl oswa konplèks.
    Objektif la nan blòk downconverters se diminye frekans konpayi asirans lan nan siyal la oswa dirèkteman retire frekans konpayi asirans lan pou jwenn siyal la baseband. Akòz sikwi senp li yo ak pri ki ba, se metòd konvèsyon desann lajman ki itilize nan ekipman sivil ak ekipman militè ak kondisyon pèfòmans ki ba.

    Aplikasyon:

    1. Televizyon satelit: LNB yo se eleman kle nan sistèm resepsyon televizyon satelit. Yo enstale nan pwen fokal nan yon antèn satelit (paraboloid oswa plat), resevwa siyal televizyon transmèt pa satelit la, epi konvèti li nan yon siyal frekans entèmedyè ki ka trete pa reseptè a.
    2. Entènèt Satelit: Nan sistèm Entènèt satelit, LNB yo itilize pou resevwa done Entènèt ki transmèt nan satelit yo. Ekipman itilizatè a resevwa done yo atravè LNB la epi li dekode ak trete li atravè modèm la.
    3. Kominikasyon satelit: LNB yo lajman itilize nan divès sistèm kominikasyon satelit, ki gen ladan telefòn satelit, emisyon satelit, transmisyon done satelit, elatriye. Yo ede resevwa ak trete divès kalite siyal kominikasyon ki transmèt nan satelit.
    4. Obsèvasyon Latè ak Teledeteksyon: Nan kèk aplikasyon pou obsèvasyon Latè ak teledeteksyon, LNB yo itilize pou resevwa done teledeteksyon ki transmèt nan satelit yo. Done sa yo ka itilize nan siveyans meteyorolojik, siveyans anviwònman an, avètisman pou katastwòf ak lòt domèn.
    An rezime, LNB yo jwe yon wòl enpòtan anpil nan sistèm kominikasyon satelit modèn epi yo lajman itilize nan emisyon televizyon, aksè entènèt, kominikasyon done ak divès domèn pwofesyonèl.

    Qualwavefouni divès kalite Block Downconverters (LNBs) nan S ~ Ka-Band la, ak yon tanperati bri nan 45 ~ 240K. Terminasyon yo ak diferan kalite pou satisfè bezwen kliyan yo.
