【应用】QMA-N射频转接器用与通讯设备调试，快速插拔，插入损耗≤0.1

时间： 2021-06-26 来源：世强

技术问答

在5G的RRU、BBU以及一体化CU中，经常需要对这些通讯设备进行通讯调试。一家做通信设备客户，由于不同生产设备厂商设计的接口界面不同，设备高频信号联网调试需要将不同接口界面信号连接起来，需要采用不同接口界面转接器来做转接，设备1的接口界面是QMA Female四孔面板安装接口类型，调试网分设备配套测试射频电缆组件是N Male转N Male的规格，如下图所示：

设备接口QMA Female接上ENA网络分析仪射频电缆组件接口N Male，需要在中间增加一个QMA Male转N Female的转接器，可以实现无缝连接。客户调试验证频率在4G，要求驻波1.50以内，插入损耗0.5，推荐Times Microwave Systems的QMA（Male）转N（Female）射频转接器 AD-QMAM-NF-6，电性能指标如下：

完全满足客户端应用技术指标要求，QMA接口是非螺纹式直插拔连接器，在设备调试时快捷高效。

Times Microwave Systems Non-Magnetic RF Interconnect Solutions

Non-magnetic coaxial cables and connectors are primarily used in applications that must transmit RF signals within a magnetic field, such MRI diagnostic imaging systems, and quantum computers. For example, quantum computers use non-magnetic components in key areas of the signal path to eliminate potential interference with applied magnetic fields. MRI systems require non-magnetic RF interconnects to send and receive pulsed RF signals； the presence of any magnetic material in these components may interfere with the magnetic field and reduce the accuracy of images.
