Imithwalo ye-coaxial kanye nendima yayo kumasekethe ahlanganisiwe we-microwave

Amasekhethi ahlanganisiwe e-Microwave (MICs) aguqule umkhakha wezokuxhumana okungenantambo futhi abe yingxenye ebalulekile yokuphila kwethu kwansuku zonke.Lezi zifunda zisetshenziswa kakhulu ezinhlelweni ezahlukahlukene ezifana nezokuxhumana ngesathelayithi, izinhlelo ze-radar, nomakhalekhukhwini.Ingxenye ebalulekile edlala indima ebalulekile ekusebenzeni kwalezi zifunda umthwalo we-coaxial.

I-coaxial load iyithuluzi elinqamula umjikelezo noma ulayini wokudlulisa nge-impedance elawulwayo.Ngokuyinhloko isetshenziselwa ukufanisa ukuvinjelwa kwesekethe ku-impedance yesici yolayini wokudlulisela.Kumasekhethi ahlanganisiwe e-microwave, imithwalo ye-coaxial iqinisekisa ukudluliswa kwamandla okulungile, inciphisa ukubonakaliswa kwesignali, futhi ikhulise ukusebenza kahle kwesekethe.

I-coaxial load iqukethe i-coaxial conductor, i-insulation material kanye ne-coaxial conductor yangaphandle.Ikhondaktha ephakathi iphethe isignali, kuyilapho ikhondakta yangaphandle inikeza isivikelo ekuphazamisekeni kwangaphandle.I-insulating material ihlukanisa abaqhubi ababili futhi igcina izici ze-impedance zesifunda.

Enye yezinzuzo eziyinhloko zokusebenzisa imithwalo ye-coaxial kumasekethe ahlanganisiwe we-microwave amandla abo okuphatha amasiginali aphezulu.Umthwalo we-coaxial uklanyelwe ukugcina i-impedance ezinzile kumafrikhwensi e-microwave, ukuqinisekisa ukusebenza kahle kwesekethe.

Ukwengeza, imithwalo ye-coaxial inikeza ukuhlukaniswa okuhle kakhulu phakathi kwamasekethe.Lokhu kubaluleke kakhulu kumasekethe ahlanganisiwe e-microwave, lapho amasekhethi amaningi aminyene ku-chip eyodwa.Ukulayishwa kwe-coaxial kusiza ukunciphisa i-crosstalk engadingeki kanye nokuphazamiseka phakathi kwalawa masekethi, ngaleyo ndlela kuthuthukiswe ukusebenza kwesekethe kukonke.

Imithwalo ye-coaxial iyatholakala ekucushweni okuhlukahlukene, okuhlanganisa isifunda esivulekile, isifunda esifushane, nokuqedwa okufanisiwe.Lokhu kunqanyulwa okuhlukile kuvumela onjiniyela ukuthi bakhethe umthwalo we-coaxial ofanele ngokusekelwe ezidingweni ezithile zesekethe abayiklamayo.

Ukulayishwa kwe-coaxial kudlala indima ebalulekile ekusebenzeni kwamasekhethi ahlanganisiwe e-microwave.Baqinisekisa ukufaniswa kwe-impedance okufanele, banciphise ukubonakaliswa kwesignali, futhi banikeze ukuhlukaniswa phakathi kwamasekhethi.Ngamandla abo okuphatha amasiginali we-high-frequency, imithwalo ye-coaxial isiyingxenye ebalulekile emiklamo yesimanje ehlanganisiwe ye-microwave.
