本文提出了一种使用环形谐振器的 20GHz 双推振荡器。该推推式振荡器采用偶极子谐振器推推式振荡器电路方案，其中一个公共谐振器起到频率确定和功率合成两个作用，从而可以省去传统推推式振荡器中所需的额外功率合成器电路。这种双推振荡器具有电路设计容易、电路结构简单、电路尺寸小型化的优点。输出功率在20.34GHz(2fo)的频率下为+4.5dBm，在1MHz的偏移频率下相位噪声为-98dBc/Hz，并且获得-33dBc的对不需要的基频信号(f 0 )的高度抑制。
In this paper, a 20GHz push-push oscillator using a ring resonator is proposed. The push-push oscillator adopts dipole resonator push-push oscillator circuit scheme, in which a common resonator plays two roles of frequency determining and power combining, and then the additional power combiner circuit required in conventional push-push oscillators can be eliminated. This kind of push-push oscillators has the advantages of the easy circuit design, the simple circuit configuation and the miniaturization of the circuit size. The output power is +4.5 dBm at the frequency of 20.34GHz (2fo) with the phase noise of -98dBc/Hz at the offset frequency of 1 MHz, and a high suppression of the undesired the fundamental frequency signal (f 0 ) of -33 dBc is obtained.
