内容：射频信号的频率往往比较大，因此常用更大的兆赫兹（MHz）和吉赫兹（GHz）单位。 ,3.1.5、REF、AMP与灵敏度的关系下图是简化后的射频前端框图，忽略了所有的滤波器器。,3.2.3、自动增益接收机具有从射频到音频的自动增益控制，为了避免设置项目名称的混淆，对于射频和中频，称为ALC（自动电平控制），对于音频，称为AGC。,他们本质上都是根据射频或音频的信号强度，自动调整设备的增益。 ,在电磁环境恶劣的地方，可以手动指定10dB或更大的衰减量，同时避免使用40dB档射频增益（AMP），保持其余部分为自动。

内容：J.C Slater分析了注入锁定时磁控管输出射频电压和频率随时间的变化关系，并对多只磁控管的注入锁定进行了理论分析[2,3]。
