摘要
射频功放模块是基站系统中的核心部件,出厂前对射频功放模块的功能进行检测意义重大。设计了一块告警功能测试板,通过观察与射频功放模块相连的测试板上的LED灯,判断射频功率放大器功能是否正常。实践证明,该方法能模仿射频功率放大器在实际基站系统中的工作行为,不仅有效地提高了射频功率放大器的良品率,而且适用于商业化大规模批量生产。
RF power amplifier module is a key component in the base station system. It is of great significance to detect the function of RF power amplifier module before shipment. This paper designs a piece of alarm function test board. Through observing the LEDs on test panel which is connected with RF power amplifier module, it is confirmed whether RF power amplifier functions are normal. Practice proves this method imitates the working be- havior of RF power amplification in the base station system, not only effectively improves the passed yield of RF power amplifier, but also is suitable for commercial large-scale batch production.
