Qaab dhismeedka aasaasiga ah ee isku xirka RF coaxial waxaa ka mid ah kaarida dhexe (xidhiidhka xarunta togan ama taban), walxaha dielectric ee ka baxsan kaari gudaha ah (qalabka dahaarka) iyo xiriirka dibadda ee dibadda (doorka gaashaanka, ie, element grounding wareegga).Isku xirka RF coaxial iyo isku xirka fiilada gudbinta coaxial ee taleefanka casriga ah si uu u ciyaaro noocyo kala duwan oo ka mid ah dekedaha moduleka RF iyo Motherboard-ka u dhexeeya doorka gudbinta signalada RF, marka lagu daro, xirayaasha RF ayaa sidoo kale loo isticmaali karaa in lagu jebiyo wareegga RF, oo ay horseed u noqdaan calaamada RF ee unugga tijaabada, si loo gaaro tijaabinta wareegga RF.
