Nyob rau hauv xyoo tas los no, nrog kev loj hlob sai ntawm kev sib txuas lus wireless thiab radar thev naus laus zis, txhawm rau txhim kho kev sib kis ntawm lub cev, nws yog qhov tsim nyog los ua kom lub zog sib kis ntawm lub system. Raws li ib feem ntawm tag nrho cov microwave system, RF coaxial connectors yuav tsum muaj peev xwm tiv taus cov kev xav tau ntawm lub zog siab. Nyob rau tib lub sijhawm, RF engineers kuj yuav tsum tau nquag ua cov kev ntsuas siab thiab ntsuas, thiab cov khoom siv microwave / cov khoom siv rau ntau yam kev xeem kuj yuav tsum muaj peev xwm tiv taus lub zog siab. Dab tsi cuam tshuam rau lub zog muaj peev xwm ntawm RF coaxial connectors? Cia los saib
●Connector loj
Rau RF signals ntawm tib zaus, cov connectors loj dua muaj zog dua. Piv txwv li, qhov loj ntawm lub connector pinhole muaj feem xyuam rau lub peev xwm tam sim no ntawm lub connector, uas yog ncaj qha ntsig txog lub hwj chim. Ntawm ntau yam siv RF coaxial connectors, 7/16 (DIN), 4.3-10, thiab N-hom connectors yog qhov loj me me, thiab qhov sib txuas pinhole qhov ntau thiab tsawg kuj loj. Feem ntau, lub zog kam rau ntawm N-hom connectors yog hais txog SMA 3-4 zaug. Tsis tas li ntawd, N-hom connectors feem ntau siv, uas yog vim li cas feem ntau passive Cheebtsam xws li attenuators thiab loads saum 200W yog N-hom connectors.
● Ua haujlwm zaus
Lub zog kam rau ua ntawm RF coaxial connectors yuav txo qis thaum lub teeb liab zaus nce. Kev hloov pauv ntawm cov teeb liab kis tau tus mob ncaj qha ua rau muaj kev hloov pauv hauv qhov poob thiab qhov hluav taws xob sawv yoj piv, yog li cuam tshuam rau lub zog xa hluav taws xob thiab cov nyhuv ntawm daim tawv nqaij. Piv txwv li, ib tug dav SMA connector tuaj yeem tiv taus txog 500W ntawm lub zog ntawm 2GHz, thiab lub zog nruab nrab tuaj yeem tiv taus tsawg dua 100W ntawm 18GHz.
●Voltage sawv wave ratio
RF connector qhia txog qee qhov hluav taws xob ntev thaum tsim. Nyob rau hauv ib txoj kab txwv-ntev, thaum tus yam ntxwv impedance thiab load impedance tsis sib npaug, ib feem ntawm qhov hluav taws xob thiab tam sim no los ntawm qhov kawg ntawm kev thauj khoom tau rov qab mus rau sab fais fab, uas yog hu ua nthwv dej. Reflected nthwv dej; voltage thiab tam sim no los ntawm qhov chaw mus rau lub load yog hu ua xwm txheej nthwv dej. Qhov tshwm sim nthwv dej ntawm qhov xwm txheej nthwv dej thiab cov nthwv dej reflected yog hu ua yoj sawv. Qhov piv ntawm qhov siab tshaj plaws tus nqi thiab qhov tsawg kawg nkaus tus nqi ntawm qhov sawv yoj yog hu ua qhov voltage sawv yoj piv (nws tseem tuaj yeem yog qhov sawv yoj coefficient). Lub reflected nthwv dej nyob hauv qhov chaw muaj peev xwm channel, ua rau lub zog xa hluav taws xob txo qis.
●Insertion poob
Insertion poob (IL) yog hais txog qhov poob ntawm lub hwj chim ntawm txoj kab vim qhov kev taw qhia ntawm RF connectors. Txhais raws li qhov piv ntawm cov zis hluav taws xob rau lub zog input. Muaj ntau yam tseem ceeb uas ua rau cov khoom sib txuas tsis zoo, feem ntau tshwm sim los ntawm: kev tsis sib haum xeeb ntawm cov yam ntxwv impedance, kev sib dhos raug yuam kev, mating kawg lub ntsej muag sib txawv, axis qaij, lateral offset, eccentricity, kev ua haujlwm raug thiab electroplating, thiab lwm yam. Vim muaj qhov poob, muaj qhov sib txawv ntawm cov tswv yim thiab cov khoom siv hluav taws xob, uas yuav cuam tshuam rau lub zog tiv thaiv.
●Altitude huab cua siab
Kev hloov pauv ntawm huab cua siab ua rau muaj kev hloov pauv hauv dielectric tas li ntawm huab cua ntu, thiab ntawm qhov tsis tshua muaj siab, huab cua tau yooj yim ionized los tsim corona. Qhov siab dua qhov siab, qhov cua siab qis dua thiab lub zog me dua.
●Tiv tauj tiv thaiv
Kev tiv thaiv kev tiv thaiv ntawm RF connector yog hais txog qhov kev tiv thaiv ntawm cov ntsiab lus sib cuag ntawm cov neeg sab hauv thiab sab nrauv thaum lub connector yog mated. Nws yog feem ntau nyob rau hauv milliohm theem, thiab tus nqi yuav tsum tsawg li tsawg tau. Nws tsuas yog ntsuas cov khoom siv ntawm cov neeg sib cuag, thiab qhov cuam tshuam ntawm lub cev tsis kam thiab solder sib koom ua ke yuav tsum raug tshem tawm thaum ntsuas. Qhov muaj nyob ntawm kev tiv thaiv yuav ua rau cov neeg sib cuag kom sov, ua rau nws nyuaj rau kev xa xov hluav taws xob loj dua hauv microwave.
●Cov ntaub ntawv sib koom
Tib hom kev sib txuas, siv cov khoom sib txawv, yuav muaj lub zog sib txawv.
Nyob rau hauv dav dav, rau lub hwj chim ntawm lub kav hlau txais xov, xav txog lub hwj chim ntawm nws tus kheej thiab lub hwj chim ntawm lub connector. Yog tias xav tau lub zog siab, koj tuaj yeem ua taukhostainless hlau txuas, thiab 400W-500W tsis muaj teeb meem.
