Abstract

In this study, the design of low pass filter that will operate in the 30-49 MHz band and attenuate the 2nd and 3rd harmonics of the signals in the band is described. Its topology is Chebyshev and it is 11th-degree filter. The harmonic attenuation value of the designed filter is -60 dB. It is designed to handle 100 W RF(CW) power. It has been implemented and. Measurement result and simulation result were compared.
