Description
technical field [0001] The invention belongs to the technical field of microwave and millimeter wave power devices, and in particular relates to a miniaturized gain equalizer based on a microstrip defect structure. Background technique [0002] Gain equalizer is a network used to correct amplitude distortion. It is usually used in conjunction with traveling wave tubes to solve the problem of amplitude distortion. It is a key technology in power drive modules. The equalizer is mainly divided into three types according to the transmission line form: microstrip type, waveguide type and coaxial type. The basic principles of the three types of gain equalizers are the same, and they are all composed of a transmission line main line and several resonant absorption units connected to the transmission line main line. The two ends of the main line of the transmission line are used as input and output ports. The resonant absorption unit is used to selectively absorb energy at a specif...
