摘　　要：微带发夹型阶梯阻抗滤波器有尺寸小、成本低、易于集成和寄生通带可调节等特点,在微波电路中有着广泛的应用。文章设计了一个X波段阶梯阻抗滤波器,中心频率为8.1GHz,带宽超过400MHz,在7.9GHz-8.3GHz的通带内插损优于3.5dB,带内波动小于1dB,在6.5GHz和9GHz处衰减大于50dB,滤波器尺寸为10mm*10mm。Microstrip hairpin stepped impedance resonator filter has found wide application in microwave communication system with the advantages of compact size,low cost,easily integrated and adjustable parasitic pass-band.This paper described X-band stepped impedance resonator band-pass microstrip filter with 8.1GHz center and a bandwidth of approximately 400 MHz,From 7.9GHz to 8.3GHz insertion loss is better than 3.5dB and the fluctuant range is less than 1 dB.The out-of-band rejection levels are larger than 50dB at 6.5GHz and 9GHz.The size of filter is 10mm10mm.
