Abstract

The development of a millimeter-wave unbalanced frequency tripler based on the nonlinear characteristics of planar Schottky varactors is presented. The entire module is designed by hybrid integration. A frequency multiplier circuit model was established to reflect the influence of diode parameters and the impedance matching on the multiplier in different frequency bands. The effect of junction imbalance on the output power of the frequency multiplier was investigated and the multiplier was improved based on the basic design. The addition of a cut microstrip stub in the improved diode unit reduced the impact of a power imbalance on frequency multiplier performance. The characteristics of the multiplier circuit were analyzed by the full-wave electromagnetic simulation of the three-dimensional structure and the harmonic balance simulation of the circuit. Test results showed that the peak output power of the improved frequency tripler was 12.6 mW at 277 GHz with an input power of 200 mW, an effective 12% improvement over the basic design.

摘要

介绍了一种基于平面肖特基变容二极管非线性特性的毫米波不平衡倍频器的研制。整个模块采用混合集成设计。建立了倍频器电路模型，以反映二极管参数和阻抗匹配在不同频段对倍频器的影响。研究了结不平衡对倍频器输出功率的影响，并在基本设计的基础上对倍频器进行了改进。在改进的二极管单元中增加了一个截断微带短截线，降低了功率不平衡对倍频器性能的影响。通过对三维结构的全波电磁仿真和电路的谐波平衡仿真分析了倍频器电路的特性。测试结果表明，改进后的三倍频器在输入功率为200 mW时，在277 GHz处的峰值输出功率为12.6 mW，比基本设计有效提高了12%。
