Equalizer is one of the most important microwave devices for improving the flatness of microwave system. The resistor loaded microstrip resonator and its application in microstrip equalizer were investigated. The equalizer made up of the resistor loaded microstrip resonator was optimized with Serenade, and the simulation results were validated using HFSS, at last a 2 to 12 GHz microstrip linear equalizer was successfully designed and fabricated. In the whole bandwidth, the performance of the system is improved about 5 dB by the equalizer, and the input and the output VSWR are no more than 2, and the final results measured in experiment are consist with the design, meeting the requirements. The results show that the method, using resistor loaded microstrip resonator, is suitable to design and fabricate linear equalizer.
