Modified Wilkinson Power Divider for Multiple Harmonics Suppression
A new structure of the Wilkinson power divider that can suppress multiple harmonics output is presented The power divider consists of T-type or π-type capacitive loads and shunt resistors. Experimental results show that this power divider suppresses the second and the third harmonic components to less than -38dB, 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.
