我们描述了隧道二极管(TD)振荡器中产生的行波脉冲的相互作用,该振荡器通过有耗电感的邻-邻耦合形成闭环。当旋转行波脉冲在一个环路中形成时,由于相邻脉冲之间的相互作用,它们的位置在旋转坐标系中略有振荡。当这样的环路用作多相振荡器时,这样的振荡可能导致在输出频谱中对应于脉冲旋转的峰值周围的寄生频谱峰值。通常,必须消除这些杂散峰值,以确保振荡器输出中有足够的带宽。为此,约化理论应用于系统的控制方程,以表征脉冲相互作用的性质,包括脉冲间振荡的频率和宇称。预测的振荡宇称导致一个有效的杂散峰消除计划的发展。在这项工作中,伪峰消除和量化的旋转脉冲的振荡行为的几个实验结果进行了讨论。
We characterize the interaction of the traveling pulses developed in tunnel diode (TD) oscillators that form a closed ring via neighbor-to-neighbor coupling by lossy inductors. When rotary traveling pulses are developed in a loop, their positions oscillate slightly in the rotating frame because of interaction between adjacent pulses. Such oscillations may result in spurious spectral peaks around the peak corresponding to the pulse rotation in the output spectrum when such a loop acts as a multiphase oscillator. Generally, these spurious peaks must be eliminated to secure sufficient bandwidth in the oscillator output. For this purpose, the reduction theory is applied to the system’s governing equations to characterize the pulse interaction properties, including the frequency and parity of the interpulse oscillation. The predicted oscillation parity leads to the development of an efficient spurious peak elimination scheme. In this work, spurious peak elimination and several experimental results quantifying the oscillatory behavior of rotary pulses are discussed.
