摘　　要：文章介绍了一种Ku频段介质稳频谐波振荡器的原理、仿真和试验结果。设计中采用电磁仿真和电路仿真结合的方式对推-推(push-push)型介质振荡器进行了整体非线性仿真,得到振荡器的输出频谱、相位噪声和输出功率的仿真结果,并进行了试验验证。通过二次谐波输出的方式提高了BJT振荡器的输出频率,得到了较好的相位噪声指标。The article introduced the theory, simulation and test result of a Ku band push-push dielectric resonate oscillator. EM simulation together with circuit simulation was used in the non-linearity simulation of the push-push DRO. The output spectrum,phase noise and output power were displayed in the simu- lation software, and the test result indicated that the second harmonic output expands the output frequency of BJT oscillator,which has a better phase noise than FET oscillator.
