RF coaxial connector yog ib tug subdivision ntawm hluav taws xob connector thiab kuj yog ib tug kub teb.Tom ntej no, engineers ntawm Cankemeng yuav ua ib qho kev qhia txog kev paub txog RF coaxial connector.
Txheej txheem cej luam ntawm RF coaxial connectors:
Coaxial connectors, (Qee cov neeg kuj hu nws RF connector los yog RF connector. Qhov tseeb, RF connector tsis raws nraim tib yam li coaxial connector. RF connector yog cais los ntawm kev xav ntawm kev siv zaus ntawm lub connector, thaum coaxial connector yog cais los ntawm Cov qauv ntawm cov connector ib co connectors tsis tas yuav coaxial, tab sis kuj siv nyob rau hauv lub tshav pob ntawm RF, thiab coaxial connector kuj yuav siv tau nyob rau hauv tsawg zaus, piv txwv li, heev nrov lub mloog pob ntseg ntsaws, zaus yuav tsum tsis txhob ntau tshaj 3MHz Los ntawm cov. Cov ntsiab lus ib txwm muaj, RF hais txog qeb MHz Niaj hnub no, cov khoom sib txuas coaxial feem ntau siv nyob rau hauv lub microwave hauv qeb GHz, lo lus "RF" tau siv txhua lub sijhawm thiab sib tshooj nrog lo lus "microwave"). uas yog ib ceg ntawm connectors.Muaj qhov sib xws thiab qhov sib txawv ntawm cov khoom sib txuas.Coaxial connectors muaj inner conductors thiab sab nraud conductors.Tus neeg xyuas pib sab hauv yog siv los txuas cov kab teeb liab.Tus neeg xyuas pib sab nrauv tsis yog tsuas yog hauv av xaim ntawm cov teeb liab kab (xav txog ntawm sab hauv ntawm tus neeg xyuas pib), tab sis tseem ua lub luag haujlwm ntawm kev tiv thaiv hluav taws xob hluav taws xob (tshuaj tiv thaiv kev cuam tshuam ntawm cov hluav taws xob hauv hluav taws xob sab hauv mus rau sab nraud los ntawm sab hauv. nto ntawm tus neeg xyuas pib sab nrauv, thiab tiv thaiv kev cuam tshuam ntawm sab nraud electromagnetic teb rau sab hauv los ntawm sab nrauv ntawm tus neeg xyuas pib), Cov yam ntxwv no muab cov coaxial connector qhov chaw zoo thiab cov qauv zoo.Sab nrauv ntawm cov lus qhia sab hauv thiab sab hauv ntawm cov lus qhia sab nraud ntawm cov coaxial txuas yog qhov chaw cylindrical - tshwj xeeb, lawv feem ntau xav tau rau kev kho tshuab thiab muaj cov axis sib xws, yog li lawv hu ua coaxial connectors.Ntawm ntau hom kab sib kis, coaxial cable tau dav siv vim nws qhov zoo tshaj plaws (cov qauv yooj yim, siv qhov chaw siab, tsim khoom yooj yim, kev sib kis tau zoo ...), uas ua rau xav tau kev sib txuas coaxial cable, thiab coaxial connector yog siv.Vim qhov zoo ntawm cov qauv coaxial, qhov txuas ntxiv ntawm cov yam ntxwv impedance ntawm (coaxial) connector (piv nrog rau lwm yam connectors) yog yooj yim guaranteed, kis tau tus mob cuam tshuam thiab cuam tshuam (EMI) yog tsawg heev, thiab kis tau tus mob tsawg, yog li nws yuav luag tsuas yog siv nyob rau hauv xov tooj cua zaus thiab microwave teb.Vim tias nws yuav luag siv nyob rau hauv siab zaus, qee qhov kev xav tau hluav taws xob ua tau zoo sib txawv ntawm lwm cov khoom sib txuas
Performance Performance index ntawm RF coaxial connector
Kev ua haujlwm hluav taws xob ntawm RF coaxial txuas yuav tsum zoo li qhov txuas ntxiv ntawm RF coaxial cable, lossis qhov cuam tshuam ntawm cov teeb liab xa mus yuav tsum raug txo kom tsawg thaum lub coaxial txuas txuas nrog coaxial cable.Yog li ntawd, tus yam ntxwv impedance thiab voltage sawv yoj piv yog cov cim tseem ceeb ntawm RF coaxial connector.Tus yam ntxwv impedance ntawm lub connector txiav txim siab hom impedance ntawm lub cable txuas nrog nws Lub voltage sawv yoj piv qhia txog qib sib piv ntawm cov connector.
A. Cov yam ntxwv impedance: tus yam ntxwv tseem ceeb ntawm cov kab sib txuas tau txiav txim siab los ntawm lub peev xwm thiab inductance ntawm cov kab sib txuas, uas qhia txog kev faib hluav taws xob thiab sib nqus hauv cov kab sib txuas.Ntev npaum li qhov nruab nrab ntawm cov kab kis tau zoo sib xws, cov yam ntxwv impedance yog qhov tsis tu ncua.Thaum lub sij hawm yoj kis tau tus mob, E / H yog tas li.Cov kab sib kis nws tus kheej txiav txim siab nws cov yam ntxwv impedance, thiab cov yam ntxwv impedance yog tib yam nyob txhua qhov chaw ntawm cov kab sib kis.Nyob rau hauv coaxial cables los yog coaxial connectors, tus yam ntxwv impedance yog txiav txim los ntawm lub puab txoj kab uas hla ntawm tus neeg xyuas pib, lub sab nraud txoj kab uas hla ntawm lub puab conductor thiab lub dielectric qhov nruab nrab ntawm lub puab thiab sab conductors.Muaj kev sib raug zoo hauv qab no.
B. Reflection coefficient: qhov piv ntawm qhov cuam tshuam qhov hluav taws xob rau qhov hluav taws xob input.Tus nqi siab dua, qhov tsis tshua muaj kev cuam tshuam lub zog, qhov zoo dua qhov sib txuam, qhov ze dua tus yam ntxwv impedance, thiab qhov zoo dua qhov txuas ntxiv.
C. Voltage sawv yoj piv: yuav muaj ob hom nthwv dej propagating ntawm cov kab sib kis tsis sib haum, ib qho yog qhov xwm txheej nthwv dej thiab lwm qhov yog qhov cuam tshuam yoj.Hauv qee qhov chaw, ob hom nthwv dej yog superimposed.Lub superimposed nthwv dej tsis propagate raws cov kab sib kis, tab sis stagnate.Hauv lwm lo lus, ib txwm muaj qhov siab tshaj plaws lossis qhov tsawg kawg nkaus voltage ntawm txhua lub dav hlau siv.Cov nthwv dej zoo li no hu ua cov nthwv dej sawv ntsug.VSWR yog qhov sib piv ntawm cov lej ntawm cov khoom siv hluav taws xob thiab cov hluav taws xob cuam tshuam rau qhov sib txawv ntawm cov khoom siv hluav taws xob thiab cov hluav taws xob cuam tshuam.Tus nqi no ntau dua lossis sib npaug rau 1, qhov me dua qhov zoo dua, thiab muaj kev sib raug zoo nrog rau qhov kev xav coefficient.
