摘要
在轨道交通通信系统中功分器、合路器被广泛应用,基于超宽带通信系统,依据宽带Wilkinson功分器设计理论,利用微带结构平面易共形特点,设计一种C波段微带形式宽带Wilkinson一分八等分功分器,要求覆盖的频率范围为5.15~5.85 GHz,端口隔离度优于20dB,各端口输出幅度差异小于0.15 dB,相位基本无差异。
In rail transit communication systems, power dividers/combiners are widely used. Based on the EUHT system and the design theory of wideband Wilkinson power dividers, and taking advantage of the easily-conformal and planar characteristics of microstrips, this paper designs a C-band microstrip wideband Wilkinson eight-way power divider, in order to cover the frequency range from 5.15to 5.85 GHz. The resulting port isolation is better than 20dB;the difference in output amplitude is less than 0.15dB and there is no phase difference between outputs.
