Abstract

In this paper, we present new structure of wideband parabolic gain equalizer for TWT applied to printed circuit board. The gain equalizer is manufactured by using design variables of transmission line obtained from derived formulae. We compared the test results of two equalizers(reference equalizer and our equalizer). From that, we confirmed the validity of presented method. The presented equalizer is 1/3 times lighter, 1/2.7 times smaller and 1/10 times chipper than those of reference equalizer(Inmet company), respectively.
