Indlela i-Coaxial Fixed Dummy Loads esebenza ngayo kuma-Microwave Integrated Circuits

Amasekethe ahlanganisiwe e-microwave (ama-MIC) ashintshe kakhulu insimu yokuxhumana okungenantambo futhi abe yingxenye ebalulekile yempilo yethu yansuku zonke. Lawa masekhethe asetshenziswa kabanzi ezinhlotsheni ezahlukene zokusebenza njengokuxhumana ngesathelayithi, izinhlelo ze-radar, kanye namafoni eselula. Ingxenye ebalulekile edlala indima ebalulekile ekusebenzeni kwala masekhethe umthwalo we-coaxial dummy.

Umthwalo we-dummy we-coaxial uyidivayisi eqeda umugqa wesekethe noma wokudlulisa nge-impedance elawulwayo. Isetshenziswa kakhulu ukufanisa i-impedance yesekethe ne-impedance ephawulekayo yomugqa wokudlulisa. Kumasekethe ahlanganisiwe e-microwave, imithwalo ye-dummy ye-coaxial iqinisekisa ukudluliselwa kwamandla okulungile, ukunciphisa ukubonakaliswa kwesignali, kanye nokwandisa ukusebenza kahle kwesekethe.

Umthwalo we-coaxial uqukethe umqhubi ophakathi, izinto zokufaka umswakama kanye nomqhubi ongaphandle. Umqhubi ophakathi uphethe isignali, kuyilapho umqhubi ongaphandle ehlinzeka ngokuvikela ekuphazamisekeni kwangaphandle. Izinto zokufaka umswakama zihlukanisa abaqhubi ababili futhi zigcina izici ze-impedance zesekethe.

Enye yezinzuzo eziyinhloko zokusebenzisa imithwalo ye-coaxial dummy kumasekethe ahlanganisiwe e-microwave yikhono lawo lokusingatha amasignali emvamisa ephezulu. Umthwalo we-coaxial dummy wenzelwe ukugcina i-impedance ezinzile kuma-frequency e-microwave, ukuqinisekisa ukusebenza kahle kwesekethe.

Ngaphezu kwalokho, imithwalo ye-coaxial dummy inikeza ukuhlukaniswa okuhle kakhulu phakathi kwamasekethe. Lokhu kubaluleke kakhulu kumasekethe ahlanganisiwe e-microwave, lapho amasekethe amaningi epakishwe khona ku-chip eyodwa. Ukulayisha i-coaxial dummy kusiza ukunciphisa ukuxoxa okungafuneki kanye nokuphazamiseka phakathi kwala masekethe, ngaleyo ndlela kuthuthukiswe ukusebenza kwesekethe iyonke.

Imithwalo ye-dummy ye-Coaxial iyatholakala ngezindlela ezahlukahlukene, kufaka phakathi i-open circuit, i-short circuit, kanye ne-matched terminations. Lezi zindlela ezahlukene zokuphela zivumela onjiniyela ukuthi bakhethe umthwalo we-coaxial ofanele ngokusekelwe ezidingweni ezithile zesekethe abayiklamayo.

Ukulayisha i-dummy ye-coaxial kudlala indima ebalulekile ekusebenzeni kwamasekethe ahlanganisiwe e-microwave. Aqinisekisa ukuhambisana okufanele kwe-impedance, anciphisa ukubonakaliswa kwesignali, futhi ahlinzeka ngokuhlukaniswa phakathi kwamasekethe. Njengoba enekhono lokusingatha amasignali avame kakhulu, imithwalo ye-dummy ye-coaxial isibe yingxenye ebalulekile ekwakhiweni kwesekethe yanamuhla ehlanganisiwe ye-microwave.
