RF coaxial connectors, monga zigawo zikuluzikulu za-zotumiza ma siginolo pafupipafupi, zimagwira ntchito yofunikira pakulankhulana, zakuthambo, kuyesa ndi kuyeza, ndi zina. Kapangidwe kake kayenera kukwaniritsa zofunikira zotayika pang'ono, kukhazikika kwapamwamba, ndi kulumikizana kodalirika kwa ma siginoloji apamwamba kwambiri-, zomwe zimapangitsa kuti pakhale zida zingapo zapadera.
Choyamba, zolumikizira za RF coaxial zimapereka -kuthamanga kwafupipafupi kwambiri. Kapangidwe kake kamagwiritsa ntchito kapangidwe ka coaxial ndi kokondakita wamkati, insulating dielectric, ndi conductor wakunja. Izi zimawonetsetsa kuti gawo lamagetsi lamagetsi limakhazikika mu dielectric pakati pa ma conductor amkati ndi akunja, potero amachepetsa ma radiation ndi kusokoneza kwakunja. Pokonza zofananira zofananira (monga 50Ω kapena 75Ω), zolumikizira za RF coaxial zimachepetsa kuwunikira ndikuwonetsetsa kuti -kutumiza kwa ma frequency apamwamba kwambiri (kuchokera ku MHz kupita ku GHz komanso kupitilira apo).
Chachiwiri, chitetezo chabwino kwambiri komanso kutaya pang'ono ndi zina mwazabwino zawo zazikulu. Kondakitala wakunja nthawi zambiri amapangidwa ndi zinthu zochititsa chidwi kwambiri monga aloyi yamkuwa kapena chitsulo chosapanga dzimbiri, ndipo plating (monga golide kapena faifi tambala) imapangitsanso kukana kwa okosijeni komanso kudalirika kolumikizana. Kapangidwe kameneka kamateteza cholumikizira ku kusokoneza kwamagetsi akunja (EMI), pomwe kusankha kwa zinthu zotchingira (monga polytetrafluoroethylene (PTFE) kapena ceramic) kumachepetsanso kuchepetsedwa kwa chizindikiro, kuonetsetsa kukhulupirika ndi kukhazikika kwa ma siginecha opatsirana.
Kuphatikiza apo, zolumikizira za RF coaxial zimapereka zolumikizira zodalirika zamakina komanso kulimba. Mapangidwe a mawonekedwe (monga ulusi, bayonet, kapena kukankha-koka) amaonetsetsa kuti pali kulumikizana kotetezeka ngakhale m'malo ovuta kwambiri monga kugwedezeka ndi kugwedezeka, kuletsa kusokonezeka kwa ma sigino chifukwa cha kumasuka. Komanso, -zapamwamba kwambiri (monga beryllium copper ndi zitsulo zosapanga dzimbiri) ndi makina olondola amawathandiza kupirira mapulagi mobwerezabwereza popanda kusokoneza magetsi, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito kwanthawi yayitali{4}}kumafakitale.
Pomaliza, zolumikizira za RF coaxial zimapereka mitundu yosiyanasiyana komanso mawonekedwe okhazikika. Kutengera ndi zomwe mukufuna kugwiritsa ntchito, mitundu yosiyanasiyana (monga SMA, BNC, N-mtundu, ndi TNC) imayang'ana kukula, kuchuluka kwa ma frequency, ndi mphamvu yogwira. Amatsatira mfundo za mayiko (monga IEC ndi MIL-STD) pofuna kuonetsetsa kuti zipangizozi n'zogwirizana komanso zimasinthasintha.
Mwachidule, ma RF coaxial connectors akhala chinthu chofunika kwambiri m'makina amakono amagetsi chifukwa cha -kuthamanga kwafupipafupi, chitetezo chapamwamba, makina odalirika komanso mapangidwe okhazikika, ndikupitiriza kulimbikitsa chitukuko cha njira zamakono zoyankhulirana ndi zamagetsi.
