Sobanura muri make ibipimo by'imikorere ya RF isolators

Muri sisitemu za RF, inshingano nyamukuru yaIbikoresho bitandukanya RFni ugutanga cyangwa kongera ubushobozi bwo kwitandukanya inzira zitandukanye z'ibimenyetso. Ni icyuma gitanga amakuru cyiza gihagarikwa no guhuza impedance kuri kimwe mu byambu byacyo. Ubusanzwe gikoreshwa muri sisitemu za radar kugira ngo kirinde imiyoboro y'amashanyarazi ku ruhande rwakira kugira ngo hirindwe ko ibimenyetso byoherezwa bifite imbaraga nyinshi, bityo bigatuma ibimenyetso byoherezwa n'ibyakirwa bishyirwa ku ruhande neza. Iyi nkuru izagufasha gusobanukirwa ibipimo by'ingenzi by'imikorere yaIbikoresho bitandukanya RF.

一. Ibisobanuro
Ibikoresho bitandukanya RFmu by'ukuri ni ubwoko bwihariye bwaImashini zizunguruka imiyoboro ya RF, aho icyambu kimwe (ubusanzwe ari impera y'inzira y'inyuma y'uruhererekane rw'ibimenyetso) gihagarikwa n'umutwaro uhuye kugira ngo haboneke uburyo bwo kohereza ibimenyetso mu cyerekezo kimwe. Bituma ibimenyetso binyura mu cyerekezo cyagenwe mu gihe bigabanya urumuri, urusaku cyangwa ibimenyetso bibangamira yerekeza inyuma, bityo bigatuma habaho kwitandukanya neza kw'aho byahoze.

Ibikoresho bitandukanya RF or imiyoboro y'amarasoubusanzwe ni ibikoresho bya ferrite bidakoresha imbaraga biyobora imiraba ya electromagnetic kuva ku mpera y’inyongera mu cyerekezo runaka binyuze mu buryo bwihariye bw’imbaraga za magnetic field n’umusaruro ku cyambu kiri hafi aho.

Ugereranyije n'ibikoresho byo kwitandukanya byahinduwe bivuye ku bisanzweImashini zizunguruka imiyoboro ya RF, ibikoresho byagenewe kwitandukanya akenshi biba bito kandi byoroshye kubihuza. Imikorere yabyo yo kwitandukanya ikorwa bitewe n'ubwiza bw'uburyo bwo guhuza terminal.

Isolateri isanzwe ifite frequency nyinshi, Isolation (12-14dB), 18 kugeza 40GHz

Ibipimo by'imikorere
Ibipimo by'ingenzi by'imikorere yaIbikoresho bitandukanya RFharimo:

Intera y'inshuro (Hz)

Impedansi (Ω)

Igihombo cyo gushyiramo (dB)

Kwishyira mu kato (dB)

Igipimo cy'umuraba uhagaze w'amashanyarazi (VSWR)

Ubushobozi bwo gukoresha imbaraga imbere (umuraba uhoraho cyangwa umusozi)

Ubushobozi bwo gukoresha imbaraga mu buryo busubira inyuma (umuraba uhoraho cyangwa umusozi)

Ubwoko bw'umuhuza

Muri byo, kwitandukanya ni kimwe mu bipimo by'ingenzi cyane, bigaragaza urwego rwo guhuza inzira za RF muri decibels (dB). Uko agaciro kaba kari hejuru, niko guhuza hagati y'ibimenyetso bito birushaho kuba byiza kandi ingaruka zo kwitandukanya zirushaho kuba nziza. Kubera ko guhuza ingufu za electromagnetic kugaragara mu nzira zose ziyobora, ni ngombwa cyane cyane gukomeza kwitandukanya cyane hagati y'inzira mu buryo bwo gutumanaho cyangwa bwo kumva neza.

Byongeye kandi, hakurikijwe ibisabwa bitandukanye byo gusaba,ibintu bitandukanyaigomba kandi kugira ubushobozi bwo gucunga ingufu bukwiye, VSWR nkeya, imiterere y’umuhuza wizewe cyane, ingano ikwiye, n’ubushyuhe bushobora guhinduka, ibyo bishobora kugira ingaruka ku mikorere yabyo mu bihe nyabyo. Ingufu ntarengwa z’umubare w’ingufu za isolateur zishobora kandi kugabanywa n’imiterere y’umutwaro warangiye.
