Imithwalo ye-coaxial kunye nendima yabo kwiisekethe ezidibeneyo ze-microwave

Iisekethe ezidibeneyo zeMicrowave (MICs) ziguqule intsimi yonxibelelwano olungenazingcingo kwaye ziye zaba yinxalenye yobomi bethu bemihla ngemihla.Ezi sekethe zisetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo ezifana nonxibelelwano lwesathelayithi, iinkqubo zeradar, kunye neeselfowuni.Inxalenye ebalulekileyo edlala indima ebalulekileyo ekusebenzeni kwezi zijikelezo ngumthwalo we-coaxial.

Umthwalo we-coaxial sisixhobo esiphelisa isiphaluka okanye umgca wokuhambisa kunye ne-impedance elawulwayo.Ikakhulu isetyenziselwa ukuhambelana nokuphazamiseka kwesekethe kwi-impedance yeempawu zomgca wothumelo.Kwiisekethe ezidibeneyo ze-microwave, imithwalo ye-coaxial iqinisekisa ukuhanjiswa kwamandla okuchanekileyo, ukunciphisa ukubonakalisa umqondiso, kunye nokwandisa ukusebenza kakuhle kwesekethe.

Umthwalo we-coaxial uquka umqhubi weziko, izinto zokugquma kunye nomqhubi wangaphandle.I-conductor yeziko ithwala umqondiso, ngelixa umqhubi wangaphandle ubonelela ngokukhusela ukuphazamisa ngaphandle.Izinto ezikhuselayo zihlula abaqhubi ababini kwaye zigcina iimpawu ze-impedance zesiphaluka.

Enye yeenzuzo eziphambili zokusebenzisa imithwalo ye-coaxial kwiisekethe ezidityanisiweyo ze-microwave kukukwazi kwabo ukuphatha imiqondiso ephezulu yamaza.Umthwalo we-coaxial wenzelwe ukugcina i-impedance ezinzileyo kwii-microwave frequencies, ukuqinisekisa ukusebenza kakuhle kwesekethe.

Ukongeza, imithwalo ye-coaxial ibonelela ngokwahlukana okuhle phakathi kweesekethe.Oku kubaluleke ngakumbi kwiisekethe ezidibeneyo ze-microwave, apho iisekethe ezininzi zipakishwe ngokuxineneyo kwichip enye.Ukulayishwa kwe-coaxial kunceda ukunciphisa i-crosstalk engafunekiyo kunye nokuphazamiseka phakathi kwezi zijikelezo, ngaloo ndlela kuphuculwe ukusebenza kwesekethe jikelele.

Imithwalo ye-coaxial ifumaneka kwiindidi ezahlukeneyo zokucwangciswa, kubandakanywa isiphaluka esivulekileyo, isiphaluka esifutshane, kunye nokupheliswa okuhambelanayo.Ezi siphelo zahlukeneyo zivumela iinjineli ukuba zikhethe umthwalo ofanelekileyo we-coaxial ngokusekelwe kwiimfuno ezithile zesekethe abayiyilayo.

Ukulayishwa kwe-coaxial kudlala indima ebalulekileyo ekusebenzeni kweesekethe ezidibeneyo ze-microwave.Baqinisekisa ukuhambelana okufanelekileyo kwe-impedance, ukunciphisa ukubonakalisa umqondiso, kunye nokubonelela ngokuzimela phakathi kweesekethe.Ngobuchule babo bokuphatha imiqondiso ye-frequency ephezulu, imithwalo ye-coaxial iye yaba yinto ebaluleke kakhulu kuyilo lwesekethe edibeneyo ye-microwave.
