本文提出了兩種型態的多路式不等功率分配器之設計。第一型態的電路在輸入埠加入四分之一波長阻抗轉換器，可以有效降低輸入阻抗，並且避免功率分配器在高功率比值時所產生的高阻抗傳輸線問題。第二型態的電路基於第一型態，將四分之一波長阻抗轉換器替換成整合帶通濾波器功能的耦合線，在原有的基礎上，加入帶通濾波器的功能。

This paper proposed the two kinds of multi-way unequal power divider.The first type of circuit add λ/4 impedance converter in front of input port.It can reduce input impedance effectively,and avoid high impedance transmission line of the power divider under high power ratio.the Second type of circuit is based on the first type that replaced λ/4 impedance converter with couple-line with integrated bandpass filter function. On the basis of the original, adding the function of band-pass filter.
