基于实频技术的小型化Wilkinson 十八路功分器设计

以工作于100MHz 的Wilkinson 十八路等功分器为设计对象，结合宽带匹配设计方法——实频技术法，设计功分器阻抗变换节，以达到小型化设计的目的。将实频技术引入阻抗变换节设计，采用集总元件构成的网络结构来取代微带功分器的四分之一波长阻抗变换节，从而大大缩减了Wilkinson 十八功分器的整体尺寸。根据仿真模型制作了十八等功分器实物，尺寸仅为10?10cm2，其插入损耗小于13.5dB，幅度波动小于0.2dB，隔离度大于18dB。

Design of Miniaturization Wilkinson Eighteen-Way Power DividerUsing Real Frequency Technique

Wilkinson eighteen-way power divider in 100MHz can be miniaturization by using Real Frequency Technique,which is an efficient method for the optimization design of broadband matching network. Uusing classic real frequency techniquefor the matching network design is smaller than quarter wavelength converter As a result, the size is cut short By measuringeighteen-way power divider, its size is only 10*10cm2, the insert loss is less then 13.5dB, the ripple is less then 0.2dB, and theinsulation is more then 18dB.
