Ukuqonda ukubaluleka kwama-coaxial fixed terminations - imithwalo ye-dummy ezinhlelweni ze-RF

Ukuqedwa okulungisiwe kwama-coaxial, owaziwa nangokuthi umthwalo we-dummy, yithuluzi elisetshenziswe ku-elekthronikhi ukulingiswa komthwalo kagesi ngaphandle kokuqeda amandla. Siqukethe into emelana nento ebiyelwe ecaleni lensimbi elixhumeke kwisixhumi sekhebula le-coaxial. Inhloso yokuqedwa okuhleliwe kwe-coaxial ukudonsa amandla omsakazo we-radio frequency (RF) futhi uyivimbele ekubonisweni emuva esifundeni.

Imithwalo ye-Dummy isetshenziswa kakhulu kuzinhlelo zokusebenza ezahlukahlukene, njengokuhlola nokulinganisa kwangaphambi komsakazo, ama-amplifiers, kanye nezimpondo. Ngokuhlinzeka ngokufana okuzinzile kokukhishwa kwedivaysi ngaphansi kovivinyo, umthwalo we-dummy uqinisekisa ukuthi amandla e-RF amunwa futhi awenzi ukuphazamiseka noma ukulimala kwemishini. Lokhu kubaluleke kakhulu ngesikhathi sesigaba sokuhlola samadivayisi we-elekthronikhi ukuvimbela ukuboniswa kwesiginali okungathinta ukunemba kwezilinganiso.

Ngaphezu kokuhlola nokulinganisa, ukunqanyulwa kwama-coaxial okungaguquki nakho kusetshenziswa ezinhlelweni ze-RF nezinhlelo zokuqeda imigqa yokudlulisela engasetshenziswanga, ukuvimbela ukuboniswa kwesiginali nokugcina ubuqotho besiginali. Ezicelo zemvamisa ephezulu, njengokuxhumana ngocingo kanye nezinhlelo ze-radar, ukusetshenziswa kwemithwalo ye-dummy kusiza ukunciphisa ukulahleka kwesiginali futhi kuqinisekiswe ukudluliswa okusebenzayo kwezimpawu ze-RF.

Idizayini yokunqanyulwa kwe-coaxial okungaguquki kubalulekile ekusebenzeni kwayo, ngezinto ezifana nokufanisa amandla, amandla okuphatha amandla, kanye nobubanzi bokujwayelekile ukudlala indima enkulu ekusebenzeni kwayo. Izinhlobo ezahlukahlukene zokuganyelwa kwama-coaxial ezingaguquki ziyatholakala, kufaka phakathi imithwalo yokumelana nesebenzayo, ngakunye okulungele izinhlelo ezithile ezisuselwa kwizimpawu zikagesi.

Ekuphetheni, ukunqanyulwa kwama-coaxial okungaguquki noma imithwalo ye-dummy yizakhi ezibalulekile ezinhlelweni ze-RF nezinhlelo ze-microwave, ukuhlinzeka izindlela ezithembekile nezizinzile zokulingisa imithwalo kagesi futhi zithole amandla e-RF. Ngokusebenzisa imithwalo ye-dummy ezinqubweni zokuhlola nokulinganisa, onjiniyela bangaqinisekisa ukunemba nokusebenza kahle kwamadivayisi kagesi, kuholela ekusebenzeni okuthuthukile nokwethenjwa ezinhlelweni ze-elekthronikhi.
