摘要
介绍了毫米波三端器件介质稳频振荡器的研制方法。采用新颖的环路反馈式电路结构,选用了使用方便的HEMT单片电路,利用器件输入/输出间的反馈和介质谐振器的稳频技术。通过对振荡器的相位噪声和输出功率的测试结果表明,这种结构完全可以应用在毫米波波段振荡器的设计中。
the study method of millimeter three-ports element oscillator stabilized with a dielectric resonator is presented. The original structure of loop-feedback is used. In the project (Ka-band HEMT oscillator), the integrated microstrip circuit is used, the high-electron-mobility-transistor microwave monolithic integrated circuit is applied and the cylindrical dielectric oscillator is used, not only as a frequency-stabilizing element, but also as a feedback circuit coupled to the O/I of the MMIC. The phasenoise and output power of the oscillator is measured.Experiment results is indicated that this method can be used in millimeter system.
