Abstract :
The theoretical synthesis, design, and computation results for the fifth- and seventh-order filters for class-E power amplifiers are presented. These filters have unequal ripples in the passband and modified attenuation in the stop band. They suppress optimally the output harmonics of the class-E power amplifiers. The filters are a resolution of the problem that N.O. Sokal (IEEE Trans. Circ. Syst. vol.CAS-27, p.235, Mar. 1980) has formulated
