In this article, we introduce and analyse the principles and design methods of PIN switch, RFSTC and STC adjusting, and give block diagram of the controlling circuit module.
Notes: (1) the Standby (pin 3) has an internal pull-up, and if it is left open circuit the module will operate when input power is applied.
注：(1)待机(引脚3)有一个内部上拉，如果是左开路模块将输入功率运行时应用。
