摘要

提出了一种基于平行带传输线的宽带混合180度和平衡传输线。提出了两种类型的混合电路:第一种是匹配0 ~ 11.5 GHz VSWR = 2时，输出幅值误差小于0.06 dB，相位误差小于0.5°，输出端口隔离值较低;第二种是匹配0 ~ 6 GHz VSWR = 2时，输出幅值误差小于0.6 dB，相位误差在0 ~ 2°，输出端口隔离度较好。该平衡器基于相同的结构，匹配0 - 11.5 GHz范围内的VSWR = 1.4。

Broadband 180 degrees Hybrids and Balun Based on a Parallel-Strips

Broadband hybrid 180 degrees and balun based on a parallel-strips transmission line are proposed. Two types of hybrids are presented: the first one is matched for VSWR = 2 from 0 to 11.5 GHz with amplitude error less than 0.06 dB and phase error lower than 0.5 degrees, but with low value of output ports isolation, and the second is matched for VSWR = 2 between 0 – 6 GHz with output amplitude error less thant 0.6 dB and phase error between 0 to 2 degrees and improved output ports isolation. The balun is based on the same structure, and is matched for VSWR = 1.4 between 0 – 11.5 GHz.
