| 摘 要： | 详细地介绍了用混频环来实现本振单元的主要思想和具体的电路力，并进行了详细的讲述，主要思想：经过鉴相器的鉴相以后，得到误差信号，经过放大器的放大以后，分成二路到VCO，控制VCO输出信号的频率。一路是高端信号频率，输出二本振信号范围在800．6～798．6MHZ，另一路是低端信号频率，输出二本振信号范围在320．6～318．6MHZ。至于选择哪一路，受计算机输出信号的控制。

| Abstract: | This paper introduces main design and concrete circuit of using mixing loop to realize the second local oscillator of the analysis receiver in detail.At first obtaining error signal after phase discrimination,and then it is divided into two ways after amplification,using to control frequencies of output signals.One is high frequent signal and another is low frequent signal.Which signal to be chosen is controlled by computer output signal. |
