Bayanin Samfura
GWB104G LNB mai fa'ida ce mai fa'ida tare da abubuwan RF guda biyu. Tare da oscillator na gida na 10.4GHz, GWB104G yana canza siginar band ɗin 10.7GHz ~ 12.75GHz Ku zuwa abubuwan 300MHz ~ 2350MHz.
Ƙarƙashin ƙaramar amo block downconverter (LNB) ita ce na'urar karɓa da aka ɗora a kan jita-jita na tauraron dan adam, wanda ke tattara raƙuman radiyo daga tasa kuma ya canza su zuwa sigina wanda aka aika ta hanyar kebul zuwa mai karɓa a cikin ginin. LNB kuma ana kiranta da ƙaramin amo block, low-amo Converter (LNC), ko ma low-amo downconverter (LND).
LNB haɗe ne na ƙaramar ƙaramar ƙararrawa, mahaɗar mitar mitar, oscillator na gida da mitar matsakaici (IF). Yana aiki azaman ƙarshen RF na gaba na mai karɓar tauraron dan adam, yana karɓar siginar microwave daga tauraron dan adam da aka tattara ta tasa, yana haɓaka shi, yana jujjuya toshe mitoci zuwa ƙaramin toshe na mitoci (IF). Wannan jujjuyawar ƙasa yana ba da damar ɗaukar siginar zuwa mai karɓar TV ta tauraron dan adam ta cikin gida ta amfani da kebul na coaxial mai rahusa; idan siginar ta kasance a ainihin mitar microwave ɗinta zai buƙaci layin jagora mai tsada kuma mara amfani.
LNB yawanci ƙaramin akwati ne da aka dakatar akan ɗaya ko sama da gajeriyar bums, ko abinci abinci, a gaban abin da ke nuna tasa, a cikin mayar da hankalinsa (ko da yake wasu ƙirar tasa suna da LNB akan ko a bayan mai nuni). Ana ɗaukar siginar microwave daga tasa ta hanyar saƙon abinci akan LNB kuma ana ciyar da shi zuwa wani yanki na jagorar wave. Fil ɗaya ko fiye na ƙarfe, ko bincike, suna fitowa cikin jagorar igiyar ruwa a kusurwoyi daidai zuwa ga axis kuma suna aiki azaman eriya, suna ciyar da siginar zuwa allon da'ira da aka buga a cikin akwatin kariya na LNB don sarrafawa. Ƙananan mitar IF siginar fitarwa yana fitowa daga soket akan akwatin wanda kebul na coaxial ke haɗuwa.
