Ma radio frequency (RF) coaxial connectors, omwe amadziwikanso kuti RF connectors, ndi zigawo zofunika kwambiri pa RF/microwave transmission transmission. Akulumikiza mizere yotumizira ma coaxial kuti athe kulumikizana pakati pa zida/ma module, kutumiza ma sign a RF ndi ma microwave moyenera. Amagwiritsidwa ntchito kwambiri polumikizirana opanda zingwe, kuwulutsa, wailesi yakanema, radar, ndi magawo ena.
Poyerekeza ndi zida zina zamagetsi, zolumikizira za RF zili ndi mbiri yayifupi. Cholumikizira choyambirira kwambiri cha RF-cholumikizira cha UHF-chidapangidwa mu 1930. M'nthawi ya Nkhondo Yachiwiri Yapadziko Lonse, chifukwa cha nkhondo yachiwiri yapadziko lonse, chifukwa chazovuta zankhondo komanso kupanga ma radar, wailesi, ndi kulumikizana ndi ma microwave, zida zapakati-zikuluzikulu monga N, C, BNC, ndi TNC zidatulukira.
Pambuyo pa 1958, zinthu zazing'ono monga SMA, SMB, ndi SMC zidawonekera. Mu 1964, mulingo wankhondo waku US wa MIL-C-39012, "General Specification for Radio Frequency Coaxial Connectors," idakhazikitsidwa. Kuyambira pamenepo, zolumikizira za RF zidayamba kukulitsa kukhazikika, kusanja, komanso kugwirizanitsa.
Ndi zigawo ziti zomwe zimapanga cholumikizira cha RF coaxial? Pali mitundu yanji? Momwe mungasankhire cholumikizira choyenera cha RF coaxial pakugwiritsa ntchito kwanu? Tiyeni tione bwinobwino.
1. Mapangidwe ndi Makhalidwe a RF Coaxial Connectors
Zolumikizira za RF coaxial nthawi zambiri zimakhala ndi kondakitala wamkati, kondakitala wakunja, insulator, ndi cholumikizira. Ma conductors amkati ndi akunja ndi oyendetsa pakati ndi chishango chakunja chachitsulo, motero, cholekanitsidwa ndi insulator kuteteza kusokoneza kwa chizindikiro ndi kutayikira. Chojambulira ndi gawo lalikulu la cholumikizira, chomwe chimagwiritsidwa ntchito kuyika kapena kuchotsa mutu wolumikizira kuti amalize kutumiza ma siginecha.
Kapangidwe kameneka kamapangitsa ma RF coaxial connectors kukhala abwino kwambiri-kawirikawiri potumiza uthenga, kutha kuletsa{1}}kusokoneza, komanso kuyikako kosavuta komanso kodalirika.
2. Kuyika Njira za RF Coaxial Connectors
Ma RF coaxial connectors atha kuikidwa m'njira zitatu: kuyika mapanelo (nthawi zambiri amakhala ndi 2-bowo/4-mabowo flanges), kukwera kwa PCB, ndi kuyika zingwe (zolumikizira zingwe). Kuyika ma panel kungagawidwenso kukhala zitsulo kudzera-pakhoma, dielectric kudzera-pakhoma, mpweya kudzera pakhoma, mitundu yotulutsa, ndi mitundu yolumikizana mwachindunji.

3. Cholumikizira Mtundu Gulu
Zolumikizira za RF coaxial zimabwera m'mitundu yosiyanasiyana, yokhala ndi mndandanda wopitilira 20 wodziwika padziko lonse lapansi komanso zina zambiri. Mitundu yodziwika bwino imaphatikizapo zolumikizira za BNC, zolumikizira za SMA, zolumikizira za N, ndi zolumikizira za TNC. Mitundu yosiyanasiyana ya zolumikizira za RF coaxial zimagwiritsidwa ntchito pazinthu zosiyanasiyana.
Mwachitsanzo, Shenzhen Xinqiyuan Technology's RF coaxial cholumikizira amapereka mitundu yolumikizira 22, kuphatikiza 1.85mm, 2.4mm, 2.92mm, 3.5mm, SMA, SSMA, SMP, SSMP (SMPM), BMA, BNC, TNC, MCX/MMCX0, 4.3/1MB yolumikizira mawonekedwe, N. Cholumikizira chilichonse chimagwirizana kwambiri ndi miyezo, kukwaniritsa zosowa zamagulu osiyanasiyana ankhondo ndi zamalonda.
