Gusobanukirwa akamaro ko guhagarika amashanyarazi mu buryo bwa Coaxial Fixed Terminations – Dummy Loads muri RF Systems

Guhagarika byemewe na coaxial, bizwi kandi nka dummy load, ni igikoresho gikoreshwa mu buhanga bw'ikoranabuhanga mu kwigana umutwaro w'amashanyarazi nta gusibanganya imbaraga. Kigizwe n'ikintu gikingira gifungiye mu gasanduku k'icyuma gahujwe n'icyuma gihuza insinga ya coaxial. Intego y'ihagarika byemewe na coaxial ni ukwinjiza ingufu za radiyo (RF) no kuzirinda ko zigaruka mu muyoboro.

Imitwaro y'udukingirizo ikunze gukoreshwa mu bikorwa bitandukanye, nko mu gupima no gupima ibyuma bitanga radiyo, amplifiers, na antene. Mu gutanga impedance ihamye ihuye n'umusaruro w'igikoresho kirimo kugeragezwa, umutwaro w'udukingirizo utuma ingufu za RF zinjira kandi ntizigire ingaruka ku bikoresho. Ibi ni ingenzi cyane mu gihe cyo kugerageza ibikoresho by'ikoranabuhanga kugira ngo hirindwe ko ibimenyetso bishobora kugira ingaruka ku buziranenge bw'ibipimo.

Uretse gupima no gupima, imiyoboro ihoraho ya coaxial ikoreshwa kandi muri sisitemu za RF na mikoroonde kugira ngo ihagarike imiyoboro itarakoreshwa, ikabuza ibimenyetso kugaragara no kubungabunga ubuziranenge bw'ibimenyetso. Mu bikorwa bikoresha inshuro nyinshi, nko muri sisitemu z'itumanaho na radar, ikoreshwa ry'imizigo idasobanutse rifasha kugabanya igihombo cy'ibimenyetso no kwemeza ko ibimenyetso bya RF byoherezwa neza.

Igishushanyo mbonera cy’aho guhagarara kw’amashanyarazi (coaxial fixed termination) ni ingenzi cyane ku mikorere yacyo, aho ibintu nko guhuza impedance, ubushobozi bwo gucunga ingufu, n’ingano y’ingufu bigira uruhare runini mu mikorere yacyo. Hari ubwoko butandukanye bw’aho guhagarara kw’amashanyarazi (coaxial fixed terminations), harimo n’imitwaro irwanya imihindagurikire y’ikirere (resistive loads) n’iy’ihindagurika ry’ikirere (reactive loads), buri kimwe gikwiriye gukoreshwa mu buryo bwihariye hashingiwe ku miterere yacyo y’amashanyarazi.

Mu gusoza, imipaka idahinduka ya coaxial cyangwa imitwaro ya dummy ni ingenzi muri sisitemu za RF na mikoroonde, bitanga uburyo bwizewe kandi buhamye bwo kwigana imitwaro y'amashanyarazi no kwinjiza ingufu za RF. Mu gukoresha imitwaro ya dummy mu igerageza no gupima, injeniyeri zishobora kwemeza ko ibikoresho by'ikoranabuhanga ari inyangamugayo kandi binoze, amaherezo biganisha ku kunoza imikorere no kwizerwa muri sisitemu z'ikoranabuhanga.
