G1 Universal LNB
Product Description
G1 series universal LNB muaj ib lossis ntxaib lossis Quattro tso zis, txhua qhov chaw RF muaj 950 ~ 2150MHz outputs nrog 13V lossis 18V thim rov qab DC lub zog los ntawm satellite txais.
Lub suab nrov qis qis qis qis qis qis (LNB) yog lub tshuab txais tau nruab rau ntawm cov tais diav satellite, uas khaws cov xov tooj cua tsis tau los ntawm lub tais thiab hloov lawv mus rau lub teeb liab uas xa los ntawm cable mus rau lub receiver hauv lub tsev. LNB tseem hu ua lub suab nrov qis, qis suab nrov converter (LNC), lossis txawm tias lub suab qis qis (LND).
Lub LNB yog kev sib xyaw ua ke ntawm cov suab nrov qis, cov khoom siv zaus, cov oscillator hauv zos thiab nruab nrab zaus (IF) amplifier. Nws ua hauj lwm raws li RF pem hauv ntej kawg ntawm satellite receiver, tau txais lub teeb liab microwave los ntawm satellite sau los ntawm lub phaj, amplifying nws, thiab downconverting lub block ntawm frequencies mus rau ib tug qis block ntawm intermediate frequencies (IF). Qhov kev hloov pauv no tso cai rau lub teeb liab nqa mus rau sab hauv tsev satellite TV receiver siv cov coaxial cable uas pheej yig; yog tias lub teeb liab tseem nyob ntawm nws qhov qub microwave zaus nws yuav xav tau ib qho kim thiab siv tsis tau waveguide kab.
LNB feem ntau yog ib lub thawv me me raug tshem tawm ntawm ib lossis ntau qhov luv luv booms, los yog pub caj npab, nyob rau hauv pem hauv ntej ntawm lub phaj reflector, ntawm nws lub hom phiaj (txawm hais tias ib co phaj designs muaj LNB los yog qab lub reflector). Lub teeb liab microwave los ntawm lub tais yog khaws los ntawm lub feedhorn ntawm LNB thiab muab pub rau ib ntu ntawm waveguide. Ib los yog ntau dua hlau pins, los yog probes, protrude mus rau hauv lub waveguide ntawm txoj cai kaum rau lub axis thiab ua raws li tus kav hlau txais xov, pub lub teeb liab mus rau ib tug luam Circuit Court board nyob rau hauv lub LNB lub shielded lub thawv rau ua. Qhov tsawg zaus IF tso zis teeb liab tshwm sim los ntawm lub qhov (socket) ntawm lub thawv uas lub coaxial cable txuas.
