RF coaxial connectors ndi zinthu zofunika kwambiri potumiza-ma siginoloji othamanga kwambiri ndipo amagwiritsidwa ntchito kwambiri polumikizirana, ma radar, mlengalenga, ndi zina. Ntchito yawo yayikulu ndikupereka kulumikizana kodalirika pakati pa zida ndikuwonetsetsa kukhulupirika kwazizindikiro.
Mapangidwe oyambira a RF coaxial cholumikizira amakhala ndi cholumikizira chamkati, kondakitala wakunja (nthawi zambiri chishango), ndi dielectric yotchingira pakati pawo. Kondakitala wamkati amatumiza -ma frequency okwera kwambiri, pomwe kondakitala wakunja amapereka chishango chapansi, kuteteza chizindikiro kuti zisasokonezedwe ndi ma elekitikitiriya akunja. The insulating dielectric, yomwe ili pakati pa okonda mkati ndi akunja, imakhalabe yodzipatula yamagetsi ndipo imathandizira woyendetsa mkati. Kapangidwe kameneka kamapangitsa kuti -kutayike komanso{5}}kuchuluke kwambiri kwa ma siginolo a RF.
Mfundo yogwiritsira ntchito imatengera kufalikira kwa mafunde a electromagnetic mu coaxial structure. Pamene chizindikiro chapamwamba-chidutsa mu kondakitala wamkati, chitetezo cha kondakitala wakunja chimatchinga gawo la ma elekitikitiriyasi kumtunda wapakati pa ma conductor amkati ndi akunja, kupanga mawonekedwe okhazikika a TEM (transverse electromagnetic) wave pattern. Njirayi imapangitsa kuti ma radiation achepe ndi kutayika pang'ono-kutayika kwa ma siginoloji. Mapangidwe a cholumikizira amayenera kufananizidwa bwino kuti awonetsetse kupitiliza pakati pa ma conductor amkati ndi akunja kuti apewe zowunikira kapena kutayika kwa mphamvu chifukwa cha kusagwirizana kwamphamvu.
Chinsinsi cha magwiridwe antchito a RF coaxial cholumikizira chagona pakufananitsa kwawo, nthawi zambiri 50Ω kapena 75Ω kuti zigwirizane ndi zofunikira zosiyanasiyana zofunsira. Kusagwirizana kwa impedance kumatha kubweretsa kuwunikira kwa ma siginecha, kuchepetsa kufalikira, komanso kuwonongeka kwa zida. Chifukwa chake, geometry ya cholumikizira, kusankha kwazinthu, ndi kulondola kwa makina amakonzedwa mwamphamvu kuti zitsimikizire kusintha kosalala kwa{4}}ma siginecha apamwamba pamalo olumikizirana.
Kuphatikiza apo, zolumikizira za RF coaxial ziyenera kuwonetsa kukhazikika kwamakina komanso kusinthasintha kwa chilengedwe, monga kukana kutentha kwambiri, chinyezi, ndi kugwedezeka, kuti zikwaniritse zovuta zogwirira ntchito. Mwachidule, ma RF coaxial connectors, kudzera m'mapangidwe apamwamba kwambiri a ma elekitiromagineti ndi makina amakina, amakwanitsa kutumiza uthenga wabwino{1}}wanthawi zonse, zomwe zimapangitsa kuti zikhale zofunika kwambiri pamagetsi amakono.
