无线通信终端传导干扰抑制

Suppression of Conducted Interference for a Certain Wireless Communication Terminal

某单位开发无线通信终端,经测试发现无线通信终端可收可发,具备基本通信能力,但工作不稳定,时常自动中断通信。通过采取降低电源线阻抗、地线阻抗,消除线路传导干扰等整改措施后,无线通信终端可以正常通信,不再掉线。

A completed design of wireless communication terminal was proved owning the basic function of communication by test. However, the operation of the terminal was instable and the automatic interruption happened frequently. By using some rectification methods, such as decreasing the impedance of power supply and ground leads, and eliminating conducted interference, the terminal could work normally without unexpected disconnection any more.
