Abstract

A modified network to suppress the nth harmonics in a Wilkinson power divider is presented. The solution has been found by adding transmission lines, whose electrical lengths are determined by using the suppression terms, between two transformers of the traditional design. Experimental results show the second and third harmonics levels achieved are -45.3 and -46.4 dB, respectively, while the performance of the power divider at the fundamental frequency is maintained.

고조파를 제거하는 기능을 갖는 윌킨슨 전력분배기를 나타내었다. 종래의 윌킨슨 전력분배기에서 선로 변환기의 양단에 제거할 고조파의 수만큼의 전송선로를 추가한 후에 새로운 윌킨슨 전력분배기의 해를 구할 수 있다. 실험적인 결과는 기본 주파수에서는 종래의 기능을 유지하면서 2차 및 3차 고조파를 -45.3 dB 및 -37 dB의 억압비를 나타내었다.
