Abstract:
Modern broadband microwave and millimeter-wave systems often struggle with excessive pass band ripple and negative gain slopes due to the loss of transmission lines such as coaxial cables, or ripples in the gain characteristic of broadband amplifiers. The common solution for this problem is using a gain equalizer to compensate for the intrinsic pass band variation with some extra loss in the band of interest in return.Designed equalizers often have a constant slope in their bandwidth. However, having ripples in pass band or in other words slope changing in some parts of the band is one of the issues that designers should deal with. In this thesis, after reviewing the previous works on the topic of equalizer design, and proposing a lossless network for the purpose of gain slope equalization as a basic solution, proposed methods for tuning the slope are introduced and then simulated; the proper method is then used to design a broadband equalizer and after construction, its performance is checked
