Abstract
The author offers to cooperate in development of an optimal harmonic-suppression output filter for power amplifiers. The commonly used elliptic-function filter is not optimal for this purpose: less attenuation is needed at higher frequencies in the stopband. An improved design should provide a value ofA_{\min}that varies with frequency as the harmonic output of the amplifier varies with frequency.Keywords
