G1 Universal LNB
Product Description
G1 yakatevedzana yepasirese LNB ine imwe kana mapatya kana Quattro yakabuda, imwe neimwe RF port ine 950 ~ 2150MHz zvinobuda ne 13V kana 18V reverse DC simba kubva kune satellite inogamuchira.
A low-noise block downconverter (LNB) ndiyo inogashira mudziyo wakaiswa pasatellite ndiro, inounganidza masaisai eredhiyo kubva mundiro yoashandura kuita chiratidzo chinotumirwa kuburikidza netambo kune anogamuchira mukati mechivako. LNB inonzi zvakare yakaderera-ruzha block, yakaderera-noise converter (LNC), kana kunyange yakaderera-noise downconverter (LND).
Iyo LNB musanganiswa wepasi-ruzha amplifier, frequency mixer, oscillator yemuno uye yepakati frequency (IF) amplifier. Iyo inoshanda seRF yekumberi kwekupedzisira kweiyo satellite inogamuchira, inogamuchira iyo microwave siginecha kubva kune satellite yakaunganidzwa nedhishi, ichiikudza, uye ichidzikisa iyo block yefrequencies kune yakaderera block yepakati mafrequency (IF). Kudzikisira uku kunobvumira chiratidzo kuti chitakurwe kune yemukati satellite TV inogamuchira uchishandisa yakachipa coaxial tambo; kana chiratidzo chikaramba chiri pairi microwave frequency yaizoda inodhura uye isingaite waveguide mutsara.
Iyo LNB inowanzova bhokisi diki rakarembera pane rimwe kana akawanda mapfupi mabhomba, kana maoko ekudya, pamberi pechiratidziro chendiro, pakutarisa kwayo (kunyangwe mamwe madhizaini ane LNB pairi kana kuseri kwechiratidziro). Iyo microwave siginecha kubva mundiro inotorwa nefeedhorn paLNB uye inopihwa kune chikamu chewaveguide. Pini imwe kana anopfuura esimbi, kana probes, anobudira mune waveguide pamakona ekurudyi kune axis uye kuita semaantenna, ichidyisa chiratidzo kune yakadhindwa redunhu bhodhi mukati mebhokisi rakadzivirirwa reLNB rekugadzirisa. Iyo yakaderera frequency IF inobuda chiratidzo inobuda kubva pane socket pabhokisi iyo iyo coaxial tambo inobatana.
