Power splitter, coupler ndi chophatikizira ndizofunikira kwambiri pamakina a RF, chifukwa chake tikufuna kugawana kusiyana kwake pakati pawo pamatanthauzidwe ndi ntchito zawo.
1.Chogawa mphamvu: Imagawanso mphamvu ya siginecha ya doko limodzi kupita ku doko lotulutsa, lomwe limatchedwanso zogawa mphamvu ndipo, zikagwiritsidwa ntchito mobwerera, zophatikiza mphamvu. Ndizida zomwe zimagwiritsidwa ntchito kwambiri paukadaulo wa wailesi. Amaphatikiza kuchuluka kwa mphamvu yamagetsi yamagetsi mu chingwe chotumizira kupita kudoko komwe kumathandizira kuti siginecha igwiritsidwe ntchito mudera lina.
2.Wophatikiza: Chophatikizira nthawi zambiri chimagwiritsidwa ntchito pa transmitter. Imaphatikiza ma siginecha a RF awiri kapena kupitilira apo omwe amatumizidwa kuchokera ku ma transmitter osiyanasiyana kupita ku chipangizo chimodzi cha RF chotumizidwa ndi mlongoti ndikupewa kulumikizana pakati pa ma siginecha padoko lililonse.
3.Coupler: Lumikizani chizindikiro ku doko lolumikizira molingana.
Mwachidule, kugawa chizindikiro chomwecho muzitsulo ziwiri kapena njira zingapo, ingogwiritsani ntchito ndi chogawa mphamvu. Kuti muphatikize ma tchanelo awiri kapena ma tchanelo angapo kukhala tchanelo chimodzi, ingokhalani ndi chophatikizira, POI ndiyophatikizanso. The coupler imasintha kagawidwe malinga ndi mphamvu zomwe zimafunidwa ndi doko kuti zitsimikizire kuti zikufika pamfundo.
Ntchito yamagetsi splitter, chophatikizira ndi coupler
1. Kuchita kwa chogawa mphamvu ndikugawanitsa molunjika chizindikiro cha satellite chapakati chapakati pamayendedwe angapo kuti atuluke, nthawi zambiri malo awiri amagetsi, magetsi anayi, mphamvu zisanu ndi imodzi ndi zina zotero.
2. The coupler imagwiritsidwa ntchito molumikizana ndi chogawa mphamvu kuti akwaniritse cholinga-kupanga mphamvu yotumizira ya gwero lachizindikiro kuti igawidwe mofanana ku madoko a antenna a dongosolo logawa m'nyumba momwe zingathere, kuti mphamvu yotumizira doko lililonse la mlongoti ndilofanana.
3. Chophatikiziracho chimagwiritsidwa ntchito makamaka kugwirizanitsa zizindikiro zamitundu yambiri mu dongosolo logawa m'nyumba. Mu ntchito za uinjiniya, ndikofunikira kuphatikiza ma frequency awiri a 800MHz C network ndi 900MHz G network kuti atulutse. Kugwiritsa ntchito chophatikizira kumapangitsa kuti makina ogawa amkati azigwira ntchito mu band ya ma frequency a CDMA ndi gulu la ma frequency a GSM nthawi imodzi.
Monga wopangaRF passive zigawo, titha kupanga mwapadera chogawa mphamvu, coupler, chophatikizira ngati yankho lanu, ndiye tikukhulupirira kuti titha kukuthandizani nthawi iliyonse.
