摘要

提出了一种新型的非对称锥形线功率分配器。它有几个带状电阻,在锥形线导体之间形成一个阶梯,以实现良好的输出隔离。通过偶/奇模分析,推导了等效电路。所制备的非对称功率分压器功率分比为1:2,在C-K波段的3∶1带宽范围内,回波损耗和隔离度均大于20 dB。

A broadband asymmetric tapered-line power divider with several strip resistors
A novel asymmetric tapered-line power divider is presented. It has several strip resistors which are formed like a ladder between the tapered-line conductors to achieve a good output isolation. The equivalent circuits are derived with the even/oddmode analysis. The fabricated asymmetric power divider with 1:2 power dividing ratio shows broadband performances in return loss and isolation which are greater than 20 dB over a 3:l bandwidth in the C-K bands.
