Design of a microwave power equalizer

In this paper, a microstrip power equalizer based on branch resonator loaded resistor is presented. According to the curved shape´s similarity between equalizers and resonators, this paper prove the valid to use multi-resonators. On the basis of this, it introduces a feasible method of broad-band equalizer. It´s adopted several branch resonators loaded resistor. The proposed equalizer operated from 6GHz to 18GHz was designed. The simulate result proved the availability of this structure. At the end, a power equalizer was fabricated. The measured results and the simulation results show a good agreement.
