摘要
介绍了锁相式频率合成器的工作原理以及频率合成器关键的性能指标。给出了利用ADF4360-7频率合成器芯片来产生全球定位系统(GPS)接收机本地振荡信号的方法。通过ADIsimPLL仿真确定了频率合成器的电路参数。并在此基础上制作了实际电路,给出测试结果,说明了该方法的有效性。
The basic working principle and the crucial parameters of phase locked synthesizer are introduced in this paper. The ADF4360-7 synthesizer chip was used to generate local oscillator of GPS receiver. The parameters of circuit were confirmed by simulation with ADIsimPLL software. Based on these, circuit was manufactured~ and test result was presented. The examination results show that the method proposed in this paper is effective.
