摘　　要：提出一种基于螺旋陷波结构的可调均衡器设计,相比传统单枝节陷波结构,该结构增大了集总电感与集总电容效应,相同条件下实现了均衡器小型化设计。同时,设计3级陷波级联结构,结合金丝键合工艺选择不同级联结构,实现均衡量可调,并给出了均衡器设计实例。均衡器工作频率为2~8 GHz,由3个级联的螺旋陷波单元构成,采用CLTE-LC基片,厚度为0.254 mm,均衡器整体尺寸为20mm×15mm×0.254mm。仿真结果显示,该均衡器均衡量有1.8dB,3.6dB,5.4 dB 3种可调模式,频带内回波损耗小于-15 dB。This paper presents an adjustable equalizer base d on spiral resonance structure, which realize miniaturization of equalizer design by increasing its equivalent capacitance and inductance under same circumstances compared with traditional single resonance structure. At the same time, three notch resonance units are designed for adjustable equilibrium quantity applied by wire bonding technique. An example of equalizer design is provided, which operates at 2–8 GHz and consists of three notch resonance units. CLTE-LC plate is applied, with 0.254 mm of thickness. The whole size of the equalizer is 20 mm×15 mm×0.254 mm. Simulation results indicate that the return losses are less than-15 dB in band, and three adjustable equilibrium quantities are achieved which are 1.8 dB,3.6 dB,5.4 dB respectively.
