Kufotokozera kwa cholumikizira cha Rf

Rf chingwezolumikizira ndi imodzi mwa njira zothandiza komanso zofala zolumikizira machitidwe a RF ndi zigawo zake.RF coaxial cholumikizira ndi chingwe cholumikizira coaxial chokhala ndi chingwe cha RF coaxial ndi cholumikizira cha RF coaxial chomwe chimatha kumapeto kwa chingwecho.Zolumikizira za Rf zimapereka zolumikizira ndi zolumikizira zina za RF, zomwe ziyenera kukhala zamtundu womwewo kapena wogwirizana pamasinthidwe ena.

Popeza mitundu yosiyanasiyana ya ntchito zomwe zolumikizira za RF zimagwiritsidwira ntchito, pali milingo yosiyanasiyana, mawonekedwe apangidwe, njira zomangira, zida, ndi njira zosinthira pambuyo pokonza zomwe zimagwiritsidwa ntchito kuti zolumikizira za RF zikhale zoyenera pazogwiritsa ntchito zina.Mwachitsanzo, zolumikizira za Hi-Rel RF nthawi zambiri zimapangidwira kuti zigwirizane ndi miyezo ingapo yankhondo kapena zida zankhondo (MIL-SPEC), zomwe zimatchula mtengo wocheperako wakulimba ndi magwiridwe antchito amagetsi.N'chimodzimodzinso ndi ntchito zina zovuta, monga zamlengalenga, ndege, zamankhwala, mafakitale, magalimoto, ndi mauthenga a telefoni, omwe ali ndi miyezo yokhwima pa gawo lililonse lofunika kwambiri lamagetsi.

Rf cholumikiziramndandanda

Rf cholumikizira mankhwala osiyanasiyana ndi wathunthu ndi wolemera, makamaka kuphatikizapo: 1.0/2.3, 1.6/5.6, 1.85mm, 10-32, 2.4mm, 2.92mm, 3.5mm, 3/4 “-20, 7/16, nthochi, BNC , BNC twinax, C, D-Sub, F mtundu, FAKRA, FME, GR874, HN, LC, Mc-card, MCX, MHV, Mini SMB, Mini SMP, Mini UHF, MMCX, N mtundu, QMA, QN, RCA , SC, SHV, SMA, SMB, SMC, SMP, SSMA, SSMB, TNC, UHF kapena UMCX mndandanda.Cholumikizira chimagwira ntchito ngati cholumikizira kuti chilumikizane ndi chingwe cha coaxial, terminal kapena bolodi losindikizidwa (PCB).

Cholumikizira chimagawidwa kukhala mutu wachimuna, mutu wachikazi, mtundu wa pulagi, mtundu wa jack, mtundu wa socket kapena non-polar ndi mitundu ina, mawonekedwe a impedance ali ndi 50 ohms kapena 75 ohms, ndipo kalembedwe kake kamakhala ndi polarity wokhazikika, polarity reverse kapena ulusi wobwerera. .Mtundu wa mawonekedwe ndi mtundu wanthawi yopuma, mtundu wa propellant kapena mtundu wokhazikika, ndipo mawonekedwe ake amagawidwa kukhala mtundu wowongoka, 90 degree arc, kapena 90 degree right angle.

 Zolumikizira za Rf zimapezeka mumayendedwe okhazikika komanso magiredi olondola ndipo zimapangidwa ndi mkuwa kapena chitsulo chosapanga dzimbiri.Mitundu ina yomanga cholumikizira cha RF imaphatikizapo kutsekedwa, bulkhead, 2-hole panel kapena 4-hole panel.
