Kumvetsetsa mawonekedwe ogwiritsira ntchito ma coaxial zolumikizira ndikofunikira kwa mainjiniya posankha cholumikizira choyenera. Nkhaniyi ifotokozanso za kagwiritsidwe ntchito pafupipafupi mu zolumikizira za RF coaxial ndikupereka tsatanetsatane wa mawonekedwe afupipafupi ndikugwiritsa ntchito kwa mafakitale pazolumikizira zosiyanasiyana.
Kodi ma frequency ogwiritsira ntchito coaxial cholumikizira ndi chiyani?
Mafupipafupi otsika a cholumikizira cha RF coaxial ndi ziro, ndipo ma frequency apamwamba kwambiri amakhala 95% ya ma frequency a cutoff.
Mafupipafupi ogwiritsira ntchito amadalira dongosolo la cholumikizira. Kuthamanga kwafupipafupi kwa cholumikizira chilichonse kumachepetsedwa ndi njira yoyamba yozungulira yozungulira yomwe imapezeka mu coaxial structure. Kuchepetsa kukula kwa chingwe kumatha kukulitsa kuchuluka kwa cholumikizira cholumikizira, pomwe kudzaza ndi zinthu za dielectric kumatsitsa ma frequency ogwiritsira ntchito ndikuwonjezera kutayika.
Choncho, kawirikawiri, ang'onoang'ono kukula kwa kondakitala akunja, ndi apamwamba ntchito pafupipafupi ntchito cholumikizira; kutsika kwa dielectric pafupipafupi kwa sing'anga yodzaza, kumapangitsa kuti ma frequency ogwiritsira ntchito akweze komanso kutsika kutayika koyika.
Kodi ndi zinthu ziti zomwe zimakhudza kuchuluka kwa ntchito?
Ma frequency ogwiritsira ntchito amatanthauza kuchuluka kwa ma frequency omwe cholumikizira cha RF coaxial chimatha kufalitsa ma siginecha mokhazikika komanso moyenera. Sizimangotsimikizira ntchito zamafakitale zomwe cholumikiziracho chili choyenera komanso zimakhudza mwachindunji kufalikira kwa chizindikiro, kutayika, komanso kukhazikika kwadongosolo.
Mafupipafupi ogwiritsira ntchito amatsimikiziridwa ndi zinthu zotsatirazi: mapangidwe apangidwe a cholumikizira (monga kukula, zida za dielectric), magawo amagetsi amagetsi (VSWR, kutayika kwa kuyika, etc.), kupanga ndi kulondola, ndi zina zotero.
M'mafakitale, ma frequency ogwiritsira ntchito ndiye chinthu chofunikira kwambiri posankha cholumikizira. Mafupipafupi ocheperako amatha kupangitsa kuti pakhale magwiridwe antchito ochepa, pomwe ma frequency omwe ali okwera kwambiri angayambitse kuwunikira kwazizindikiro ndi kutayika kowonjezereka.
Makhalidwe Afupipafupi ndi Kugwiritsa Ntchito Coaxial Connectors
