여러 개의 하모닉을 억제하는 윌킨슨 전력 분배기

Abstract

In this thesis, a novel power divider is proposed that can suppress the 9 harmonic output. The power divider employs λ/4n 개방 스터브s, which are located at the 3λ/4 branches and parallel connection of resistor which shunts the output ports.

According to experimental results, it was found that the power divider showed a harmonic suppression characteristic lower than -37dB for 9 harmonics output (1st to 9th harmonic), while maintaining the characteristics of a conventional Wilkinson power divider

featuring an equal power split, a simultaneous impedance matching at all ports and a good isolation between output ports. The experimental results showed a good agreement with the simulation results.
