Abstract:The influence of resistors for microstrip equalizer and resistor loaded microstrip designing method is investigated through numerical simulations and experiments based on the analyse of the resistor loaded L microstrip resonator and its application to the microstrip equalizer.By studying the location and resistance of the resistors,we constructed a microstrip equalizer with a thin-film resistor in the resonator.It is not only the frequency can be adjustable,but also the attenuation and quality factor can be adjustable.At last a microstrip equalizer composed of this thin-film resistor loaded L resonator was designed,and good results were obtained in the experiment,which show that this thin-film resistor loaded resonator is suitable to microstrip equalizer.
Keywords:Microstrip equalizer  Microstrip resonator  Resistor loaded  Quality factor
