Ewe. Nangona kunjalo, iinkqubo ze-eriyali zangaphambili zasebenzisa i-fit feeder, ezingezizo iintambo ze-coaxial.
Iintambo ze-coaxial zeRF kufuneka ziqondwe zibe ngamacandelo amabini.
I-RF: I-RF ibhekisa kumaza ombane anokukhanya esithubeni, ukusuka kuma-300kHz ukuya kuma-300GHz.
I-RF yirediyo yefrikhwensi yangoku, ishorthand ye-ifrikhwensi yokutshintshana kwamaza ombane.
Utshintshiselwano lwangoku olutshintsha ngaphantsi kwe 1000 amaxesha ngesekondi ibizwa ngokuba sezantsi{1}}ifrikhwensi yangoku, kwaye loo nto itshintsha ngaphezulu kwamaxesha ayi-10000 ngesekondi ibizwa ngokuba phezulu{3}}yangoku yangoku. I-RF iphezulu kakhulu-umsinga wangoku.
I-RF (300K-300G) yibhendi ephezulu yamaza phakathi koluhlu oluphezulu (ngaphezu kwe-10K).
Kwithiyori ye-elektroniki, xa ikhoyo ngoku ihamba nge-conductor, intsimi yamagnetic yenziwa malunga nomqhubi; xa ukutshintshwa kwangoku kuhamba nge-conductor, intsimi ye-electromagnetic etshintshanayo yenziwa malunga nomqhubi. Oku kubizwa ngokuba yi-electromagnetic wave.
Amaza ombane anamaza angaphantsi kwe-100kHz afunxwa ngumphezulu woMhlaba kwaye akanako ukusasazwa ngokufanelekileyo. Nangona kunjalo, amaza e-electromagnetic anamaza angaphezulu kwe-100kHz anokusasaza emoyeni kwaye aboniswe yi-ionosphere kumda ongaphandle we-atmosfera, evumela ukuhanjiswa{3}}kumgama omde.
Sibiza -amaza ombane wombane aphezulu anesakhono sosasazo{1}}somgama omde (RF).
Itekhnoloji yeRF isetyenziswa kakhulu kunxibelelwano olungenazingcingo; iinkqubo zikamabonakude zentambo zisebenzisa usasazo lweRF.
Intambo ye-coaxial: Ngenxa yokuba ii-coaxial cables ezimbini (i-coaxial conductor yangaphakathi / i-conductor yangaphandle) i-asymmetrical ngokubhekiselele kumhlaba, kunye ne-coaxial conductor yangaphakathi ebekwe kwi-axis yomnye umqhubi wangaphandle we-cylindrical, ibizwa ngokuba yi "coaxial cable."
Uphawu lweentambo ze-coaxial kukuba indawo ye-electromagnetic ivalwe ngaphakathi kwi-conductor yangaphandle, ivumela ukusetyenziswa kumaza aphezulu.
Qaphela: Umqhubi wangaphandle wentambo yecoaxial zombini yiconductor kunye ne-shielding layer (isebenza njenge-loop zombini kwaye ibonelela -ukuphazamiseka kokusebenza).
Intambo yecoaxial esetyenziselwa ukuhambisa imiqondiso yeRF ibizwa ngokuba yi "RF coaxial cable."
Isignali efunyenwe yi-eriyali igqithiselwa kwisiphelo sangaphambili ngelayini ye-feeder, kwaye imveliso yesignali evela kumphambili iphinde idluliselwe kwizixhobo ezahlukeneyo zokufumana ngelayini yesondlo.
Kule mihla, sihlala sibona uqhagamshelo kunye nezixhasi zothumelo ezisetyenziswa kwiinkqubo zokukhulisa umqondiso ezifana-neemitha zombane ezingasebenzi ngeengcingo (iChina Mobile, China Unicom, China Telecom, njalo njalo.), itonela, kunye namagumbi angaphantsi.
