Chogawa Mphamvu cha RFTYT cha Njira 3

Chogawa mphamvu cha njira zitatu ndi chinthu chofunikira chomwe chimagwiritsidwa ntchito mu makina olumikizirana opanda zingwe ndi ma RF circuits. Chimakhala ndi doko limodzi lolowera ndi ma doko atatu otulutsira, omwe amagwiritsidwa ntchito kugawa ma signal olowera ku ma doko atatu otulutsira. Chimakwaniritsa kulekanitsa ma signal ndi kugawa mphamvu mwa kukwaniritsa kugawa mphamvu kofanana komanso kugawa kosalekeza. Nthawi zambiri chimafunika kukhala ndi mafunde abwino, kudzipatula kwambiri, komanso kukhala bwino mu band flat.

Zizindikiro zazikulu zaukadaulo za chogawa mphamvu cha njira zitatu ndi kuchuluka kwa ma frequency, kupirira mphamvu, kutayika kwa magawo, kutayika kwa insertion pakati pa input ndi output, kudzipatula pakati pa ma ports, ndi standing wave ratio ya doko lililonse.

Zogaŵira mphamvu za njira zitatu zimagwiritsidwa ntchito kwambiri mu makina olumikizirana opanda zingwe ndi ma RF circuits. Nthawi zambiri zimagwiritsidwa ntchito m'magawo monga makina a base station, ma antenna arrays, ndi ma RF front-end modules.
Chogawa mphamvu cha njira zitatu ndi chipangizo chofala cha RF, ndipo makhalidwe ake akuluakulu ndi ubwino wake ndi awa:

Kugawa kofanana: Chogawa mphamvu cha njira zitatu chimatha kugawa zizindikiro zolowera mofanana ku ma doko atatu otulutsa, zomwe zimapangitsa kuti ma signal azitha kugawidwa bwino. Izi ndizothandiza kwambiri pa mapulogalamu omwe amafunikira kupeza kapena kutumiza zizindikiro zofanana nthawi imodzi, monga machitidwe a antenna array.

Broadband: Ma splitter amphamvu a njira zitatu nthawi zambiri amakhala ndi ma frequency ambiri ndipo amatha kuphimba ma frequency ambiri. Izi zimapangitsa kuti akhale oyenera kugwiritsa ntchito ma RF osiyanasiyana, kuphatikizapo machitidwe olumikizirana, machitidwe a radar, zida zoyezera, ndi zina zotero.

Kutayika kochepa: Kapangidwe kabwino ka magetsi kogawa mphamvu kangathandize kuchepetsa kutayika kwa malo olowera. Kutayika kochepa ndikofunikira kwambiri, makamaka pamakina otumizira ma signal ndi ma receiver omwe ali ndi ma frequency apamwamba, chifukwa kungathandize kuti ma signal azitha kugwira bwino ntchito komanso kuti ma signal azitha kumveka bwino.

Kupatula kwakukulu: Kupatula kumatanthauza kuchuluka kwa kusokoneza kwa zizindikiro pakati pa ma doko otulutsa a chogawa mphamvu. Chogawa mphamvu cha njira zitatu nthawi zambiri chimapereka kusiyanitsa kwakukulu, kuonetsetsa kuti kusokoneza kochepa pakati pa zizindikiro kuchokera ku ma doko osiyanasiyana otulutsa, motero kusunga mawonekedwe abwino a chizindikiro.

Kukula kochepa: Njira zitatu zogawa mphamvu nthawi zambiri zimagwiritsa ntchito ma CD ndi kapangidwe kake kakang'ono, ndi kukula kochepa komanso kuchuluka kochepa. Izi zimathandiza kuti ziphatikizidwe mosavuta mu machitidwe osiyanasiyana a RF, kusunga malo ndikuwongolera magwiridwe antchito onse a makina.
Makasitomala amatha kusankha njira yoyenera yogawa ma frequency ndi mphamvu malinga ndi zofunikira pakugwiritsa ntchito, kapena kulumikizana mwachindunji ndi ogwira ntchito athu ogulitsa kuti mumvetse bwino komanso kugula.
