Design and Implementation of the GHz-Band Wide (2~18 GHz) Linear Equalizer

Abstract

This paper presents a linear amplitude equalizer developed to secure the linearity of the slope of the amplitude over the frequency band ranging <TEX>$2\sim18\;GHz$</TEX>. The circuit model is featured by the resistor placed between each pair of a transmission-line and a stub. The design includes finding the values of resistors and stubs to have the optimal linear slope and return loss performances. The measured data show the acceptable performances of the slope variation and return loss over <TEX>$2\sim18\;GHz$</TEX>.
