Gbangba Aabo Meji Diplexer 490-500MHz
UHF band cavity duplexer duplexer JX-CD4-490M500M-85B jẹ ọkan iru awọn paati palolo RF ti a ṣe apẹrẹ & ti a ṣe fun tita nipasẹ Jingxin, eyiti o ni awọn ẹya pataki pẹlu pipadanu ifibọ kekere kere ju 3.8dB ni iwọn kekere, wọn LxWxH: 325mm x 245mm x 129mm (O pọju 135 mm).
Awọn igbohunsafẹfẹ ti duplexer yii bo lati 490.7-491MHz , 496.3-496.62
MHz, 493.7-494MHz, 499.3-499.62MHz,
Duplexer meji yii ni a ṣe pẹlu awọn asopọ SMB-Female, ṣugbọn eyiti o le yipada si awọn miiran ni ibamu si ibeere, iru duplexer le jẹri ni aaye fun igba pipẹ.
Gẹgẹbi ileri, gbogbo awọn paati palolo RF lati Jingxin ni atilẹyin ọja ọdun 3.
