| 摘 要： | 振荡器是通信系统中的关键器件，其性能对整个系统有着重要影响。文中介绍了利用负阻原理设计2.425 GHz振荡器的方法。根据负阻原理，使用Agilent公司的ADS软件，采用[WTHX]S[WTBZ]参数仿真和谐波分析方法，对振器振荡器进行了仿真设计。根据仿真结果加工了振荡器，并用频谱仪对其进行测量和分析。测得相位噪声为-122 dBc/Hz@100 kHz，谐波抑制为23.6 dB，达到了预期目标。

| Abstract: | This paper introduced the method of designing a 2.425 GHz oscillator by the principle of negative resistance. Based on the principle, with the help of the ADS software of Agilent company, using the [WTHX]S[WTBZ] parameter simulation and harmonic balance analysis method, we designed the oscillator. We processed the oscillator according to the simulation results, moreover, we measured and analyzed it with spectrum analyzer. Phase noise less than -122 dBc/Hz@100 kHz,harmonic suppression more than 23.6 dB. |
