IP67 Biyo-ilaaliya UHF Shaandheeyaha Dalabka Baadhitaanka oo Ka Shaqeynaya 449-451MHz

JX-CF1-449M451M-90NWP UHF filter waa hal nooc oo ka mid ah filter godka bandpass ee daboolaya laga bilaabo 449-451MHz oo leh baaska band ee 2MHz. Iyada oo muujinta luminta gelinta wax ka yar 0.5dB, diidmo sare oo ka badan 90dB, soo noqoshada luminta in ka badan 15dB, awoodda shaqada ee 50w, waxay diyaar u tahay xirayaasha N kale, oo lagu qiyaasay 145mm x 110mm 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 caadiga ah ee goobta, miirayaasha godka IP 67 badan ayaa loo habeyn karaa codsi ahaan. Sidii ballan-qaadku ahaa, dhammaan qaybaha RF dadban ee Jingxin waxay leeyihiin dammaanad 3 sano ah.
