A scheme is proposed for generating low-phase-noise oscillatory signals in sub-millimeter-wave frequencies, which utilizes the dynamics of a traveling pulse rotating in a closed system of oscillators, which consists of transmission lines periodically loaded with resonant-tunneling diodes (RTDs) that is coupled with evenly spaced straight RTD lines. The spatial extendedness of the oscillator component results in an effective method of self-injection locking, by which the phase noise is reduced significantly. Herein, the principle of operation is described with its numerical/experimental validation, together with the potential to generate harmonic signals. To detect pulse dynamics definitely, the experiment was carried out in MHz frequencies utilizing tunnel diodes in place of RTDs.

谐振隧道二极管传输线环路中旋转行进脉冲的自注入锁定

提出了一种用于产生亚毫米波频率的低相位噪声振荡信号的方案,该方案利用了在封闭的振荡器系统中旋转的行进脉冲的动力学特性,该系统由周期性加载谐振隧道二极管的传输线组成( RTD)与均匀间隔的直线RTD线耦合。振荡器组件的空间扩展性导致了一种有效的自注入锁定方法,通过该方法可以大大降低相位噪声。在此,通过其数值/实验验证以及产生谐波信号的可能性来描述操作原理。为了确切地检测脉冲动力学,该实验是在MHz频率下利用隧道二极管代替RTD进行的。
