Imirimo ya radiyo igendanwa ihuza imiyoboro ya RF Microwave ifite umuvuduko mwinshi

Guhagarika RF ni ubwoko bw'igice cyo gupima neza imikorere y'imashini zipima imiyoboro ya vector, ahanini kigizwe n'imiyoboro y'umwuka na ferrite y'umuzenguruko imbere.

Impedance iranga umurongo w'umwuka igenwa n'umurambararo w'umuyoboro w'imbere n'umurambararo w'imbere w'umuyoboro w'inyuma. Impedance isanzwe ifite umuyoboro wayo w'imbere uhujwe n'ikintu gifite irangi rirwanya, kandi hari imyobo yo gukosora hagati y'irangi kugira ngo wongere agaciro k'impedance yo guhuza ihererekanya. Umurongo w'umwuka w'impedance za mikoroonde utuma impedance iranga umurongo wayo irushaho kuba nziza kuruta ihererekanya risanzwe.

Uduti twa magnetic twa Ferrite dushobora gukurura ingufu nyinshi za magnetic field. Iyo dukoresheje magnetic ya ferrite mu gihe cyo gupima, uburebure bwa offset, coefficient ya reflection, n'icyiciro cy'umurongo w'umwuka byose birahinduka.

Mu kunyereza ferrite magnetic rod, impedance no kugaruka bishobora kunozwa kugira ngo harebwe neza ko calibration ikora neza mu rugero rwo hejuru rw'amasaha. Mu kwimura aho iherezo ribera kugira ngo hahindurwe reflection phase ya reflection coefficient, Radio frequency loads ishobora gutandukanya ikosa ryo gupima iherezo muri sisitemu cyangwa gupima, kandi ikoreshwa cyane mu kugenzura neza vector network analyzers. Bitewe n'ubushobozi bwayo bwo guhindura neza impedance isanzwe, sliding terminals ikora neza mu mikoreshereze ya high frequency.
