提出了一种改进的微波双平衡混频器中使用的阻抗变换微带平衡带状线锥度计算机辅助建模方法。谱域方法已用于确定具有有限接地平面宽度的悬挂微带线的参数。计算表明，所分析结构中的色散效应并不显着。在 1.5mm 厚的氧化铝基板上设计和实现的 50–100ω 过渡分别在高达 10 和 15GHz 时表现出非常好的或可接受的性能。已经提出并通过实验验证了一种抑制屏蔽过渡情况下出现的不良模式的方法。
An improved approach to the computer-aided modelling of impedance-transforming microstrip-balanced stripline tapers used in microwave doubly balanced mixers is presented. The spectral domain method has been used to determine the parameters of a suspended microstrip with finite ground plane width. Calculations show that dispersion effects in the analysed structure are insignificant. The designed and realised 50–100ω transition on a 1.5mm thick alumina substrate exhibited very good or acceptable performance up to 10 and 15GHz, respectively. A method to suppress undesired modes appearing in the case of shielded transitions has been proposed and experimentally verified.
