A cholumikizira cholunjikandi chipangizo chopanda mphamvu chomwe chimagwirizanitsa gawo la mphamvu yotumizira ndi kuchuluka kodziwika; kudzera mu doko lina, nthawi zambiri chimagwiritsa ntchito mizere iwiri yotumizira yomwe imagwirizanitsidwa bwino kotero kuti mphamvu imadutsa mu imodzi yolumikizidwa ndi inzake.
Makhalidwe:
A cholumikizira cholunjikaimadziwika ndi coupling factor yake, isolation, ndi directionabilityKulumikiza sikokhazikika koma kumasiyana malinga ndi kuchuluka kwa ma frequency. Ngakhale mapangidwe osiyanasiyana amatha kuchepetsa kusiyana, kulumikizana kosalala bwino sikungapangidwe. Ma couplers olunjika amafotokozedwa malinga ndi kulondola kwa coupling ya frequency band center. Mwachitsanzo, coupling ya 10 dB ± 0,5 dB imatanthauza kutiZolumikizira zowongoleraikhoza kukhala ndi cholumikizira cha 9,5 dB mpaka 10,5 dB pakati pa bandi ya ma frequency. Kulondola kumeneku kumachitika chifukwa cha kulekerera kwa miyeso komwe kumatha kusungidwa patali pakati pa mizere iwiri yolumikizidwa. Clutch ina, Mafotokozedwe ake ndi kukhudzidwa kwa ma frequency. Kukhudzidwa kwa ma frequency okwera kwambiri kumalola bandi yayikulu yogwirira ntchito. Zigawo zingapo zolumikizira za kotala-wavelength zimagwiritsidwa ntchito kuti zikwaniritse bandiwifi ya ma frequency yotakata. Zachizolowezi Mtundu uwu wa zolumikizira za Directional wapangidwira chiŵerengero cha bandwidth ya ma frequency ndi frizz yayikulu yolumikizira mkati mwa mabandi a ma frequency.
Cholumikizira chowongolerandi chida chothandiza poyezera opanga makina a RF. Sikuti chimangopereka chithunzi cha kukula kwa mphamvu ya RF yokha, komanso chimalekanitsa zigawo za chizindikiro cha kutsogolo ndi chowonekera zomwe zimathandiza kufotokozera katundu.
Si Chuan Keenlion Microwave ndi makina ambiri osankhidwa m'makonzedwe a narrowband ndi broadband, okhala ndi ma frequency kuyambira 0.5 mpaka 50 GHz. Amapangidwira kuti azitha kugwiritsa ntchito mphamvu yolowera ya ma watts 10 mpaka 30 mu makina otumizira mawaya 50. Mapangidwe a microstrip kapena stripline amagwiritsidwa ntchito, ndipo amakonzedwa kuti agwire ntchito bwino kwambiri.
 
Tikhozanso kusintha rfcholumikizira cholunjikamalinga ndi zomwe mukufuna. Mutha kulowa patsamba losinthira kuti mupereke zofunikira zomwe mukufuna.
