典型的现代通信信号链由发射和接收端组成,两个部分都需要RF(射频)功率监测和控制(图1)。目前,在两部分电路中,RF功率的监测通常都采用将功率监测和基于基准电压设定点的自动增益控制(AGC)技术结合起来的技术。接收端的信号监测往往是在中频(IF)完成的,而发射端的功率监测则可
A typical modern communications signal chain consists of the transmitter and receiver, both of which require RF power monitoring and control (Figure 1). Currently, RF power monitoring in both parts of the circuit typically employs a combination of power monitoring and automatic gain control (AGC) based on a reference voltage set point. The signal monitoring at the receiving end is usually done at intermediate frequency (IF), while the power monitoring at the transmitting end
