Fotokozani mwachidule magawo a magwiridwe antchito a RF isolator

Mu machitidwe a RF, ntchito yayikulu yaRF isolatorsndikupereka kapena kukulitsa luso lodzipatula panjira zosiyanasiyana zazizindikiro. Ndiwozungulira wowongolera womwe umathetsedwa ndi kufananiza kofananira pa amodzi mwa madoko ake. Nthawi zambiri amagwiritsidwa ntchito m'makina a radar kuti ateteze madera okhudzidwa polandira kuti apewe kusokonezedwa ndi ma siginecha omwe ali ndi mphamvu zambiri, potero amakwaniritsa kudzipatula kwa ma sign omwe amatumizidwa ndi kulandira. Nkhaniyi idzakutengerani kuti mumvetsetse magawo a magwiridwe antchito aRF isolators.

一. Tanthauzo
RF isolatorsali makamaka mawonekedwe apadera aRF zozungulira, momwe doko limodzi (kawirikawiri njira yobwerera kumbuyo kwa unyolo wa siginecha) imathetsedwa ndi katundu wofananira kuti akwaniritse kufalikira kwa ma siginecha. Imangolola ma sign kuti adutse njira yomwe idakonzedweratu ndikupondereza zowunikira, phokoso kapena zosokoneza kuchokera kumbali yakumbuyo, potero zimakwaniritsa kudzipatula kwa ulalo wam'mbuyo.

RF isolators or ozunguliraNthawi zambiri zimakhala zida za ferrite zomwe zimawongolera mafunde a electromagnetic kuchokera komwe kumalowera kulowera kwinakwake kudzera mu kasinthidwe ka maginito ndi zotuluka padoko loyandikana nalo.

Poyerekeza ndi zodzipatula zosinthidwa kuchokera ku ochiritsiraRF zozungulira, zipangizo zomwe zimapangidwira kuti zikhale zodzipatula nthawi zambiri zimakhala zowonjezereka komanso zosavuta kuziphatikiza. Kuchita kwake kudzipatula kumakhudzidwa mwachindunji ndi mtundu wa ma terminal afananiza.

High frequency standard isolator, Isolation (12-14dB), 18 mpaka 40GHz

二. Magwiridwe magawo
Zizindikiro zazikulu zogwirira ntchito zaRF isolatorszikuphatikizapo:

Ma frequency osiyanasiyana (Hz)

Kusokoneza (Ω)

Kutaya (dB)

Kudzipatula (dB)

Voltage Stand Wave ratio (VSWR)

Kuthekera kwamphamvu yakutsogolo (mafunde opitilira kapena pachimake)

Kuthekera kosinthira mphamvu (mafunde opitilira kapena pachimake)

Mtundu wa cholumikizira

Pakati pawo, kudzipatula ndi chimodzi mwazinthu zofunika kwambiri, zomwe zikuwonetsa kuchuluka kwa kulumikizana pakati pa njira za RF mu ma decibel (dB). Kukwera kwa mtengo, kumachepetsa kugwirizanitsa pakati pa zizindikiro ndi bwino kudzipatula. Popeza kulumikizana kwa ma electromagnetic ndikofala m'njira zonse zoyendetsera, ndikofunikira kwambiri kudzipatula pakati pa njira zolumikizirana bwino kwambiri kapena makina omvera.

Kuphatikiza apo, malinga ndi zofunikira zosiyanasiyana zofunsira,odzipatulaAyeneranso kukhala ndi mphamvu yogwiritsira ntchito mphamvu, VSWR yotsika, mawonekedwe odalirika odalirika, kukula koyenera, ndi kutentha kwa kutentha kosinthika, zomwe zingakhudze momwe amachitira pazochitika zenizeni. Mlozera wamphamvu kwambiri wa isolator ukhozanso kuchepetsedwa ndi mawonekedwe a katundu wothetsedwa.
