摘要
对毫米波宽带四倍频器的设计方法并进行了理论分析及计算仿真。介绍了利用平衡式结构对奇次谐波进行抑制,从而实现宽带偶次倍频的原理,提出了选择肖特基二极管的原则。利用HFSS仿真和优化电路结构,采用微带线鳍线结构实现了宽频带的毫米波二倍频器。在此基础上,采用两级倍频的方式实现了宽带毫米波四倍频器。设计的Ka波段毫米波四倍频器输入频率6.625～10 GHz,输入功率为10 dBm时,在26.5～40 GHz频率范围内,输出功率大于10 dBm,对三次和五次谐波的抑制大于20 dBc。
The design method of a broadband millimeter-wave quadrupler was discussed. The theoretical analysis and simulation were performed. The principle of realizing the broadband even frequency multiplier using balanced structure to reject odd harmonic frequency and the fundamental rules of selecting Schottky-barrier diodes were introduced. A millimeter wave broadband doubler was achieved using microstrip-fin line structure which was simulated and optimized with HFSS software. The broadband millimeter-wave quadrupler was realized using the two stages doubler. The result shows that the Ka-band quadrupler has the output power of more than 10 dBm, the third and fifth harmonic frequency rejection of more than 20 dBc between 26.5 GHz and 40 GHz, when the input frequency is from 6. 625 GHz to 10 GHz.
