Indlela esebenza ngayo iCoaxial Fixed Dummy Loads kwiMicrowave Integrated Circuits

Iisekethe ezidityanisiweyo ze-microwave (ii-MIC) ziye zaguqula icandelo lonxibelelwano olungenazingcingo kwaye zibe yinxalenye ebalulekileyo yobomi bethu bemihla ngemihla. Ezi sekethe zisetyenziswa kakhulu kwiindlela ezahlukeneyo zokusetyenziswa ezifana nonxibelelwano lwesathelayithi, iinkqubo zeradar, kunye neefowuni eziphathwayo. Icandelo elibalulekileyo elidlala indima ebalulekileyo ekusebenzeni kwezi sekethe ngumthwalo we-coaxial dummy.

Umthwalo we-coaxial dummy sisixhobo esiphelisa umgca wesekethe okanye wothumelo nge-impedance elawulwayo. Isetyenziswa kakhulu ukufanisa i-impedance yesekethe kunye ne-impedance eqhelekileyo yomgca wothumelo. Kwiisekethe ezidityanisiweyo ze-microwave, imithwalo ye-coaxial dummy iqinisekisa ukudluliselwa kwamandla ngokuchanekileyo, ukunciphisa ukubonakaliswa kwesignali, kunye nokwandisa ukusebenza kakuhle kwesekethe.

Umthwalo we-coaxial uquka umqhubi osembindini, izinto zokuthintela ubushushu kunye nomqhubi wangaphandle. Umqhubi osembindini uphethe isignali, ngelixa umqhubi wangaphandle ekhusela ukuphazamiseka kwangaphandle. Izinto zokuthintela ubushushu zahlula aba baqhubi babini kwaye zigcina iimpawu ze-impedance zesekethe.

Enye yezona nzuzo ziphambili zokusebenzisa imithwalo ye-coaxial dummy kwiisekethe ezidityanisiweyo ze-microwave kukukwazi kwazo ukuphatha imiqondiso ye-frequency ephezulu. Umthwalo we-coaxial dummy wenzelwe ukugcina i-impedance ezinzileyo kwiifrequency ze-microwave, ukuqinisekisa ukusebenza kakuhle kwesekethe.

Ukongeza, imithwalo ye-coaxial dummy ibonelela ngokwahlukana okuhle phakathi kweesekethe. Oku kubaluleke kakhulu kwiisekethe ezidityanisiweyo ze-microwave, apho iisekethe ezininzi zipakishwe kakhulu kwi-chip enye. Ukulayisha i-coaxial dummy kunceda ukunciphisa i-crosstalk engafunekiyo kunye nokuphazamiseka phakathi kwezi sekethe, ngaloo ndlela kuphucula ukusebenza kwesekethe iyonke.

Imithwalo ye-Coaxial dummy ifumaneka ngeendlela ezahlukeneyo, kubandakanya i-open circuit, i-short circuit, kunye ne-matched terminations. Ezi terminations zahlukeneyo zivumela iinjineli ukuba zikhethe umthwalo we-coaxial ofanelekileyo ngokusekelwe kwiimfuno ezithile zesekethe abayilayo.

Ukufakwa kwe-coaxial dummy kudlala indima ebalulekileyo ekusebenzeni kweesekethe ezidityanisiweyo ze-microwave. Ziqinisekisa ukuhambelana okufanelekileyo kwe-impedance, zinciphisa ukubonakaliswa kwesignali, kwaye zibonelela ngokwahlulwa phakathi kweesekethe. Ngenxa yokukwazi kwazo ukuphatha imiqondiso ye-high-frequency, imithwalo ye-coaxial dummy ibe yinxalenye ebalulekileyo kwiindlela zanamhlanje zoyilo lweesekethe ezidityanisiweyo ze-microwave.
