本文提出了一种使用谐波平衡商业软件对非线性微波电路进行全局稳定性分析的新技术。任何二参数平面中的稳定运行区域是通过分叉条件和新的连续技术的组合来确定的。在异步不稳定的情况下，完全追踪准周期解路径并分析其稳定性，从而可以预测可能的混沌响应。新方法使得任何电路设计人员都可以进行迄今为止仅限于内部模拟器的两种分析。在这里，它已应用于基于变容二极管的倍频器，与实验结果非常吻合。
In this paper, a new technique is presented for the global stability analysis of nonlinear microwave circuits using harmonic balance commercial software. The stable operation region in any two-parameter plane is determined from a combination of the bifurcation conditions and a new continuation technique. In the case of asynchronous instability, the quasi-periodic solution paths are entirely traced and their stability is analyzed, which allows the prediction of possible chaotic responses. The new method makes both kinds of analysis, limited so far to in-house simulators, accessible to any circuit designer. Here, it has been applied to a varactor-based frequency doubler with excellent agreement with the experimental results.
