本文提出了一种新型的二次谐波功率合成振荡器使用相互同步的古恩二极管嵌入槽线谐振器。振荡器采用了双面MIC技术。振荡器由古恩二极管、槽线谐振器和微带线组成。通过在槽线谐振器上嵌入古恩二极管，可以非常容易地产生谐波RF信号。微带线用于功率合成输出电路。该振荡器具有电路设计容易、电路结构简单、电路尺寸小型化等优点。设计并制作了K波段二次谐波振荡器。在19.0GHz（2f 0）的设计频率下，输出功率为+5.75dBm;在1 MHz的偏频下，相位噪声为-111.7dBc/Hz。实现了对-39dBc的非期望基频信号（f0）的良好抑制。
This paper represents a novel second harmonic power combining oscillator using mutually synchronized Gunn diodes embedded on slot line resonators. A both-sided MIC technology is adopted in the oscillator. The oscillator consists of Gunn diodes, slot line resonators and microstrip lines. By embedding Gunn diodes on the slot line resonators, the harmonic RF signal can be generated very easily. The microstrip lines are used for the power combining output circuit. This oscillator has advantages such as easy circuit design, simple circuit configuration and miniaturization of the circuit size. The second harmonic oscillator is designed and fabricated in K-Band. The output power is +5.75dBm at the design frequency of 19.0GHz (2f0) with the phase noise of -111.7dBc/Hz at the offset frequency of 1MHz. Excellent suppression of the undesired fundamental frequency signal (f0) of -39dBc is achieved.
