IP67 Biyo-ilaaliya UHF Shaandheeyaha Daabka Baadhitaanka ee Ka Shaqeynaya 339-402MHz
JX-CF1-339M402M-90NWP UHF filter waa hal nooc oo ka mid ah filter godka bandpass ee daboolaya laga bilaabo 339-402MHz oo leh xariiqda 2MHz. 15dB, awoodda shaqada ee 50w, waxay diyaar u tahay xirayaasha N kale, oo lagu qiyaasay 160mm x 150mm x 59mm.
Shaandheeyahan waxaa si gaar ah loogu talagalay xalka bannaanka oo leh budada lagu dahaadhay biyaha IP67, kaas oo la kulmi kara ceeryaamo milix ah EN 60068-2-11 / Ka Cass ST4, qoyaan 95% RH 2 wareeg ah 2 24H 25 ° C ilaa 55 ° C marka loo eego TS EN 50155: 2017 Tijaabada kulaylka qoyaanka wareegga ah (13.4.7). Nooca noocaan ah ee shaandhada aan biyuhu lahayn ayaa si fiican loo tijaabiyey sida heerka caadiga ah ee garoonka dhexdiisa, filtarrada godka biyuhu badan yihiin ayaa loo habeyn karaa codsi ahaan. Sidii ballan-qaadku ahaa, dhammaan qaybaha RF dadban ee Jingxin waxay leeyihiin dammaanad 3 sano ah.
