BNC (Bayonet Neil Conselman)
BNC connector muaj kev ruaj ntseg thiab ceev ceev bayonet mechanism. Nws yog siv nrog coaxial cable hauv xov tooj cua, TV, RF electronics, ntsuas ntsuas thiab video signals. Nws muaj qhov impedance ntawm 50 ohms lossis 75 ohms. Qhov kev txwv zaus feem ntau yog 4 GHz, tab sis tuaj yeem siab dua yog tias siv cov qauv zoo dua.
SMA (Sub-Miniature A)
SMA connectors yog hais txog ib nrab ntawm qhov loj ntawm BNC connectors thiab haum rau RF kev sib txuas ntawm Circuit Court boards, microwave lim, attenuators, mixers thiab oscillators.SMA connectors muaj ib tug threaded kev twb kev txuas los muab ib tug muaj zog kev twb kev txuas. Lawv muaj 50-ohm impedance thiab 18 GHz zaus txwv.
SMB (Super Miniature B)
SMB connectors tseem me dua SMA connectors. Lawv muaj ib tug snap fastening mechanism rau ceev plugging thiab unplugging. Cov connectors no me me heev uas lawv tau siv tshwj xeeb rau kev sib txuas ntawm board-to-board lossis cov khoom sib txuas hauv cov khoom siv. Cov connectors no muaj impedance ntawm 50 lossis 75 ohms thiab zaus txwv rau 4 GHz.
N-hom
Rau kev ua tau zoo dua connectors, koj yuav tsum siv N-hom connector. Nws yog siv rau hauv cov khoom siv tshaj tawm thiab kev sib txuas lus, lub zog xa hluav taws xob, cov khoom txais, thiab kev siv RF. Muaj nyob rau hauv 50 los yog 75 ohm impedance, N-Type connectors kuj muaj ib tug threaded coupling mechanism. Thaum lawv cov 11 GHz zaus txwv qis dua SMA connectors, precision versions tuaj yeem ua haujlwm ntawm zaus mus txog 18 GHz.
TNC (Threaded Neill-Concelman)
Thaum kawg, threaded version ntawm BNC connector yog TNC connector. Nws muaj qhov impedance ntawm 50 ohms thiab zaus txwv ntawm 11 GHz. lub bayonet mounting ntawm BNC connectors feem ntau qhia suab nrov nyob rau hauv lub teeb liab kis tau tus mob. TNC connector daws qhov teeb meem no. Yog li ntawd, TNC connectors muaj peev xwm ua tau ntawm ntau zaus dua BNCs.
Thaum koj tau txiav txim siab txog hom RF connector, cov kauj ruam tom ntej yog los txiav txim seb qhov twg yuav tsum tau ua rau koj daim ntawv thov. Koj puas xav tau ib tug txiv neej los yog poj niam connector? Ncaj lossis txoj cai kaum txuas? Cov kev xav tau ntawm koj daim ntawv thov yuav txiav txim siab cov kev txiav txim siab no. Cov ntawv thov feem ntau yuav ua haujlwm zoo nrog cov khoom sib txuas ncaj nraim, tab sis yog tias qhov chaw nruj, koj tuaj yeem xaiv rau lub kaum sab xis txuas. Txawm li cas los xij, txoj cai-angle connectors raug teeb meem ntau dua.
Txawm hais tias koj tsim koj tus kheej cov khoom siv los yog tawm mus rau cov kws tshaj lij, peb vam tias qhov no tau pab tau los qhia koj rau lub ntiaj teb ntawm RF connectors. Nco ntsoov nco ntsoov tias cov no tsuas yog cov khoom sib txuas ntau tshaj plaws hauv kev lag luam niaj hnub no. Peb tsis tau them ntau qhov sib txawv hauv qhov blog no. Yog tias koj tab tom nrhiav rau ib pab neeg muaj kev paub dhau los los tswj koj cov kev cai RF cable sib dhos, tiv tauj peb kom tau txais cov lus hais dawb.
