摘　　要：为了克服传统折线式超短波多路耦合方案滤波器必须频率从高到低依次接入短路枝节、容易产生频率碰撞、前级需要庞大的开关矩阵、与固定宽带滤波器合路困难等缺点,提出一种全可调折线形超短波多路耦合方案,保证无论滤波器频率如何排布都能进行最佳匹配,最后输入到公共输出端,并可以与固定宽带滤波器再进行合路,或直接输出到天线,保证所有可调窄带滤波器的同等工作地位。In order to overcome the shortcomings of the traditional polyLine ultrashort wave multiplexer scheme,such as the filter must access the short-circuit branch from high to low frequency,easily produce frequency collision,the front stage requires a huge switching matrix,difficulty in merging with fixed wideband filter.A fully adjustable polyLine ultrashort wave coupling scheme is proposed.It ensures the best match regardless of the filter frequency arrangement.Finally it inputs to the common output,and it can be combined with the fixed wideband filter again,or output directly to the antenna.It ensures equal working status for all tunable filters.
