Uburyo Coaxial Fixed Dummy Loads ikora muri Microwave Integrated Circuits

Uduce twa mikoroonde (MICs) twahinduye urwego rw'itumanaho ridafite insinga kandi twabaye igice cy'ingenzi cy'ubuzima bwacu bwa buri munsi. Uduce dukoreshwa cyane mu bikorwa bitandukanye nko mu itumanaho rya satelite, sisitemu za radar, na telefoni zigendanwa. Igice cy'ingenzi gikora uruhare runini mu mikorere y'utwo duce ni umutwaro wa coaxial dummy.

Umutwaro wa coaxial dummy ni igikoresho gihagarika umurongo wa circuit cyangwa transmission hamwe na impedance igenzurwa. Gikoreshwa cyane cyane mu guhuza impedance y'umurongo wa circuit n'umutwaro uranga umurongo wa crowned. Mu miyoboro ya microwave ivanze, imitwaro ya coaxial dummy ituma ingufu zikwirakwizwa neza, bikagabanya reflection y'ibimenyetso, kandi bikongera imikorere myiza ya circuit.

Umutwaro wa coaxial ugizwe na conductor yo hagati, ibikoresho byo gukingira n'inyuma. Conductor yo hagati itwara ikimenyetso, mu gihe conductor yo hanze itanga uburinzi ku mvururu zo hanze. Ibikoresho byo gukingira bitandukanya conductors zombi kandi bigakomeza imiterere ya impedance y'uruziga.

Imwe mu nyungu z'ingenzi zo gukoresha imizigo ya coaxial dummy muri mikoroonde integrated circuits ni ubushobozi bwazo bwo gufata ibimenyetso bya frequency yo hejuru. Umuzigo wa coaxial dummy wagenewe kugumana impedance ihamye kuri mikoroonde, bigatuma uruziga rukora neza.

Byongeye kandi, imizigo ya coaxial dummy itanga uburyo bwiza bwo kwitandukanya hagati y’imiyoboro. Ibi ni ingenzi cyane cyane mu miyoboro ya micro-onde, aho imiyoboro myinshi ipakiye ku gice kimwe. Imiyoboro ya coaxial dummy ifasha kugabanya ibiganiro bidakenewe n’ingaruka mbi hagati y’imiyoboro, bityo bikanoza imikorere y’imiyoboro muri rusange.

Imitwaro ya Coaxial dummy iboneka mu buryo butandukanye, harimo imikorere ifunguye, imikorere migufi, n'imikorere ihuye. Iyi iherezo itandukanye yemerera injeniyeri guhitamo imikorere ya coaxial ikwiye hashingiwe ku bisabwa byihariye by'uruziga barimo gushushanya.

Gushyiramo uduce duto twa coaxial bigira uruhare runini mu mikorere ya microwave. Bituma habaho guhuza neza impedance, bigabanya reflection y'ibimenyetso, kandi bigatanga umwihariko hagati y'uduce duto. Bitewe n'ubushobozi bwabyo bwo gufata ibimenyetso bikoresha frequency nyinshi, double dummy loadings za coaxial zabaye ingenzi cyane mu miterere ya microwave igezweho.
