EX high pass filtering fine protection
Broadband high-performance radio frequency (RF) transmission path and direct current (DC) coaxial feed path composite cascade (RF+DC PATH) fine protection device, using RF coupled DC isolation path and DC (DC) coaxial feed path parallel multiplexing technology to realize the synchronous protection of RF transmission path and DC path; The rapid response cascade transient suppression technology and push-pull voltage limiting technology are used to limit the lightning electromagnetic pulse [LEMP] and its surge voltage within the embedded voltage range of the suppression device, so as to realize the effective all-weather lightning electromagnetic pulse (LEMP) and its surge fine protection of the key coaxial components of wireless equipment and system.
DX includes four series of products: DC power path special protection DS, RF transmission path and DC feed path composite protection DX, RF path and DC bias branch composite protection DXJ, and extended band DE.
