Abstract

This paper presents a structure of the Wilkinson power divider that can suppress the 9ea harmonic output. The power divider consists of ${\lambda}/4n$ open stubs, which are located at the $3{\lambda}/4$ branches and parallel connection of resistor which shunts the output ports. Experimental results show that this power divider suppresses from 1st to 9th harmonic components to less than -37dB, 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. these results agree quite well with the simulation results.
