摘要
介绍了谐波混频器的混频原理和设计方法,应用高频场仿真软件及谐波平衡计算软件,研究并实际制作了带有一维光子带隙结构的Ka频段微带全集成高中频四次谐波混频器。实验测得:固定中频频率为3GHz,射频频率在34～35.8GHz的频带内变化时,变频损耗小于14.5dB,最小变频损耗为11dB。表明这种高中频谐波混频电路的设计方案切实可行。
This paper gives the particular description of a theoretical analysis and practical design for high IF frequency millimeter-wave subharmonic mixer with three one-dimensional photonic bandgap （PBG） cells. Base on computer aided design, a Ka-band 4th harmonic mixer has been designed and tested. When IF frequency is 3 GHz, and RF frequency varied from 34～35.8 GHz, the conversion loss is less than 14.5 dB and the least is ll dB. The results of simulation and test show that the formulas are correct and the scheme is practicable.
