Kodi Fyuluta ya RF / Microwave ndi chiyani?

Mawailesi pafupipafupi (RF) & zosefera za ma microwave zimatanthauzidwa ngati mtundu wa fyuluta yamagetsi, yomwe idapangidwa kuti izigwira ntchito pamasinthidwe amtundu wa megahertz kupita ku gigahertz (ma frequency apakati mpaka apamwamba kwambiri). Zosefera izi ndizomwe zimagwiritsidwa ntchito ndi mawayilesi ambiri, wailesi yakanema, kulumikizana opanda zingwe (mafoni am'manja, Wi-Fi, ndi zina zambiri), motero zida zambiri za RF ndi ma microwave zimaphatikizanso kusefa kwa ma siginecha omwe amatumizidwa kapena kulandilidwa. Zosefera zotere zimagwiritsidwa ntchito ngati midadada yomangira ma duplexer ndi diplexer kuphatikiza kapena kulekanitsa ma frequency angapo.

Ntchito:
1. Fyuluta ya Rf imatha kuchepetsa kusokoneza kwa ma frequency band ndikuwongolera magwiridwe antchito a zida zomwe zili limodzi.
2. Fyuluta ya RF imalola kuti ma frequency ndi tchanelo omwe akutumizidwa kapena kulandiridwa kuti adutse ndikuchepetsa kusokoneza kwa ma sign kunja kwa tchanelo.

Pamaziko a ntchito yake, malinga ndi kuchuluka kwa ma frequency a siginecha yogwira ntchito kuyika zosefera za RF, zimagawidwa m'magulu anayi, ndiye fyuluta yotsika (LPF), fyuluta yapamwamba (HPF), fyuluta yodutsa ( BPF) ndi band stop fyuluta (BSF).

1. Zosefera zotsika : Zimatanthawuza fyuluta yomwe siginecha yotsika imatha kudutsa koma siginecha yapamwamba kwambiri siyingadutse;
2. High-pass fyuluta: Ndizosiyana, ndiko kuti, zizindikiro zapamwamba zimatha kudutsa ndipo zizindikiro zotsika kwambiri sizingadutse;
3. Band-pass fyuluta: Imatanthawuza kuchuluka kwa ma frequency angapo a ma siginoloji omwe amatha kudutsa, fyuluta ya RF ndi kunja kwa ma frequency angapo azizindikiro sangathe kudutsa;
4. Band-stop fyuluta: Kuchita kwa bandi-stop fyuluta ndizosiyana, ndiko kuti, zizindikiro mumagulu amagulu zimatsekedwa, koma zizindikiro za kunja kwa maulendowa zimaloledwa kudutsa;

Zosefera za RF zitha kugawidwa kukhala zosefera za SAW, fyuluta ya BAW, fyuluta ya LC, fyuluta yamkati, fyuluta ya ceramic molingana ndi kapangidwe kawo kapena zinthu zawo.

Jingxin, monga katswiriwopanga zigawo za RF passive components, atha kupereka zosefera pamwambapa za RF kuti zifotokozedwe, zomwe zakhala zikupanga zaka zopitilira 10 kupanga ndi kupanga zosefera za RF pazogwiritsa ntchito zosiyanasiyana, monga yankho la DAS, dongosolo la BAD, kulumikizana kwankhondo, ndikupeza kutamandidwa kwakukulu chifukwa chakuchita bwino. makasitomala. Zosefera kapangidwe kachitidwe zitha kuchitidwa ndi Jingxin malinga ndi tanthauzo, mafunso ambiri amalandiridwa.
