MMCX 微小型射频同轴连接器
MINIATURE MICROAX RF XIAL CONNEORS
MMCX 系列射频连接器是一种比MCX更小的微型产品。它体积小、重量轻、连接方便。广泛用于对系统体积、重量都有要求的小型通讯、网络设备中连接射频同轴电缆。
The series of MMCX radio frequency joining device is a kind of microminiaturized produ aller than MCX. It is all, light, joins convenient and reliable. Use for to system volume, serious to have all-scale communication, network equipment that require join the xial cable of the radio frequency extensively.
