Kodi cholinga cha cavity resonator ndi chiyani? 2878-2882MHz Cavity Filter mu Modern Passive Networks

Chophimba cha cavity resonator chimasunga mphamvu ya RF mu mawonekedwe a mafunde oyima ndipo chimaibweza kokha pa ma frequency omwe akufunidwa.Fyuluta ya M'mimba ya 2878-2882MHzChopangidwa ndi Keenlion yochokera ku Chengdu chimagwiritsa ntchito mfundoyi kudzera mu cavity ya kotala-wave coaxial: makoma ophimbidwa ndi siliva amatanthauza 2880 MHz eigen-mode, pomwe mphamvu ya off-band imabwereranso ku gwero. Chifukwa 2878-2882MHz Cavity Filter ilibe zigawo zogwira ntchito, kutayika kwa insertion kumangokhala pa kutayika kwa conductor ndi dielectric - mitengo yoyezedwa imakhalabe pansi pa 1.0 dB kudutsa zenera la 4 MHz.

Kapangidwe kaukadaulo ndi magwiridwe antchito

Filter ya 2878-2882MHz Cavity imagwiritsa ntchito ma cavity apamwamba a Q kuti ichepetse kutayika kwa insertion (≤1.0 dB) komanso kusankha bwino (>40 dB kukanidwa pa ±5 MHz offset). Nyumba yake yaying'ono, yolemera 74 × 31 × 30 mm, imalumikizana bwino ndi makina ocheperako monga ma UAV pods kapena ma IoT radio ang'onoang'ono. Fyulutayi imagwira ntchito modalirika kutentha kwa -55°C mpaka 85°C, ndipo VSWR imasungidwa pansi pa 1.5:1 kuti ichepetse kuwunikira kwa chizindikiro. Chida chilichonse chimayesedwa 100% kuti chitsimikizire zofunikira monga power handling (20W CW) ndi band-edge steepness.

Envelopu ya Makina

Kukula konse ndi 74 × 30 × 31mm—kocheperako kuposa zida zambiri za SAW—komabe 2878-2882MHz Cavity Filter imagwirira ntchito 20 W CW. Mabowo awiri a M2 omwe ali pakati pa 15 mm amalola 2878-2882MHz Cavity Filter kuti imamangiriridwe mwachindunji ku khoma la aluminiyamu, kuchotsa kufunikira kwa bulaketi yosiyana ndikusunga magalamu amtengo wapatali mu UAV kapena nyumba zomangidwa ndi manja.

Msana wa Factory

Makina a fakitale a Keenlion a zaka 20, mbale, ma tune ndi ma welds nthawi iliyonse ya 2878-2882MHz Cavity Filter pansi pa denga limodzi. Nthawi yotsogolera ndi masiku asanu ndi awiri pazida zokhazikika, maola makumi anayi mphambu asanu ndi atatu pa maoda obwerezabwereza. Kutayika kwa kuyika ≤1.0 dB ndi kukanidwa ≥40 dB kumatsimikizika pa 2878-2882MHz Cavity Filter iliyonse; zitsanzo zaulere zimatumizidwa mkati mwa maola makumi anayi mphambu asanu ndi atatu ndipo kugawanika kwa ma frequency opangidwa mwamakonda kumavomerezedwa popanda MOQ.
