Lub luag haujlwm tseem ceeb ntawm cov khoom sib txuas tuaj yeem muab faib ua peb pawg: kev ua haujlwm txhua yam, hluav taws xob ua haujlwm thiab ib puag ncig kev ua haujlwm.
2, hluav taws xob ua haujlwm
Lub ntsiab hluav taws xob ua haujlwm ntawm lub connector muaj xws li kov tsis kam, rwb thaiv tsev tsis kam thiab dielectric zog.Cov haujlwm hluav taws xob feem ntau cuam tshuam nrog kev txawj electroplating.Nyob rau hauv qhov tseeb, ntau connectors tsuas yog cia siab rau lub conduction nyhuv ntawm txheej conductive txheej.
① Kov qhov tsis kam.Cov khoom siv hluav taws xob zoo tshaj plaws yuav tsum muaj qhov kov qis thiab ruaj khov.Qhov kov tsis kam ntawm lub connector yog li ntawm ob peb milliohms mus rau kaum milliohms.Nyob rau lub sijhawm no, nws yog qhov tseem ceeb ntawm kev tiv thaiv ntawm cov txheej txheej.
② rwb thaiv tsev tsis kam.Lub hom phiaj ntawm kev ntsuas lub rwb thaiv tsev ua haujlwm ntawm qhov kov ntawm qhov hluav taws xob txuas thiab nruab nrab ntawm qhov kov thiab lub plhaub, qhov kev txiav txim ntawm qhov loj ntawm ntau pua megohms mus rau ntau txhiab megohms.
③ Lub zog hluav taws xob.Kuj hu ua withstand voltage thiab dielectric withstand voltage, nws characterizes lub peev xwm los tiv thaiv ntxiv voltages ntawm tus kov qhov chaw ntawm connector los yog ntawm lub kov qhov chaw thiab lub plhaub.
④ Lwm yam khoom siv hluav taws xob.Lub electromagnetic cuam tshuam to attenuation yog los soj ntsuam cov electromagnetic cuam tshuam shielding nyhuv ntawm connector, thiab nws yog feem ntau kuaj nyob rau hauv lub zaus ntawm 100MHz ~ 10GHz.
Rau cov xov tooj cua zaus coaxial txuas, kuj tseem muaj lub hom phiaj hluav taws xob xws li cov yam ntxwv impedance, nkag mus poob, kev cuam tshuam coefficient, thiab voltage sawv yoj piv (VSWR).Vim yog kev txhim kho cov txuj ci digital, txhawm rau txuas thiab xa cov teeb liab siab ceev digital pulse, ib hom tshiab txuas, uas yog lub teeb liab ceev txuas, tau nthuav tawm.Raws li, nyob rau hauv cov nqe lus ntawm hluav taws xob ua haujlwm, ntxiv rau cov yam ntxwv impedance, qee lub hom phiaj hluav taws xob tshiab kuj tau nthuav tawm., xws li crosstalk (crosstalk), kis tau tus mob ncua (ntev), lub sij hawm lag (skew) thiab lwm yam.
