Vuga muri make ibipimo byimikorere ya RF izigunga

Muri sisitemu ya RF, umurimo wingenzi waAkato ka RFni ugutanga cyangwa kuzamura ubushobozi bwo kwigunga kubimenyetso bitandukanye. Numuzunguruko watezimbere urangizwa no guhuza impedance kuri kimwe ku byambu byayo. Ubusanzwe ikoreshwa muri sisitemu ya radar kugirango irinde imiyoboro yunvikana kumpera yakira kugirango hirindwe kubangamira ibimenyetso byanduza ingufu nyinshi, bityo bigere ku bwigunge bwiza bwibimenyetso byanduye kandi byakiriwe. Iyi ngingo izagutwara kugirango wumve imikorere yibanze yaAkato ka RF.

一. Ibisobanuro
Akato ka RFni muburyo bwihariye bwaAbakwirakwiza RF, aho icyambu kimwe (mubisanzwe inzira ihindukira iherezo ryurunigi rwibimenyetso) ihagarikwa numutwaro uhuye kugirango ugere ku cyerekezo kimwe. Gusa yemerera ibimenyetso kunyura mucyerekezo cyateganijwe mugihe cyo guhagarika ibitekerezo, urusaku cyangwa ibimenyetso byivanga bivuye muburyo butandukanye, bityo bikagera ku bwigunge bukomeye bwihuza ryabanje.

Akato ka RF or abakwirakwizani ibikoresho bya pasitoro ya ferrite iyobora amashanyarazi ya electronique kuva kumurongo winjira mucyerekezo cyihariye binyuze mumiterere yihariye ya magnetique hamwe nibisohoka kumurongo wegeranye.

Ugereranije n'akato kahinduwe kuva mubisanzweAbakwirakwiza RF, ibikoresho byakozwe muburyo bwihariye bwo kwigunga mubisanzwe biroroshye kandi byoroshye guhuza. Imikorere yayo yo kwigunga igira ingaruka itaziguye nubwiza bwa terefone ihuye.

Umuyoboro mwinshi usanzwe wigunga, Kwigunga (12-14dB), 18 kugeza 40GHz

二. Ibipimo by'imikorere
Ibyingenzi byingenzi byerekana imikorere yaAkato ka RFharimo:

Ikirangantego (Hz)

Impedance (Ω)

Gutakaza kwinjiza (dB)

Kwigunga (dB)

Umubare w'amashanyarazi uhagaze (VSWR)

Imbere yo gukoresha imbaraga zo gukomeza (umurongo uhoraho cyangwa impinga)

Hindura imbaraga zo gukoresha imbaraga (guhora kumurongo cyangwa impinga)

Ubwoko bwumuhuza

Muri byo, kwigunga ni kimwe mu bipimo bikomeye, byerekana urwego rwo guhuza inzira ya RF muri decibels (dB). Kurenza agaciro, niko guhuza guhuza ibimenyetso nibyiza byo kwigunga. Kubera ko guhuza amashanyarazi biganje mu nzira zose ziyobora, ni ngombwa cyane cyane gukomeza kwigunga cyane hagati yinzira mu itumanaho ryuzuye cyangwa sisitemu yo kumva.

Mubyongeyeho, ukurikije ibisabwa bitandukanye,abigungaigomba kandi kuba ifite ubushobozi bukwiye bwo gukoresha ingufu, VSWR yo hasi, imiterere-yizewe ihuza imiterere, ingano ikwiye, hamwe nubushyuhe bwimikorere ikora, bishobora kugira ingaruka kumikorere yabyo. Umubare ntarengwa w'imbaraga zo kwigunga nazo zishobora kugarukira kubiranga umutwaro urangiye.
