【摘要】 本文设计了一种微带形式的3mm波段的2倍频器,采用了直流馈电与变容二极管单管的组合结构,在保证了最大输出功率的同时,使得倍频器的谐波抑制度达到较好的指标。该电路使用MA46H146变容二极管用导电胶粘在介电常数为2.2,厚度为0.127mm的RT/Duriod5880基片上。仿真结果显示:输入端频率50-54GHz、功率为12dBm,在输出端频率100-108 GHz范围内,最大输出功率为4dbm。更多还原

【Abstract】 A millimeter-wave microstrip frequency doubler design using a varactor diode is proposed in this paper which is specifically designed for wide output frequency bandwidth with minimal sacrifice in performance.The circuit is designed to operate at output frequencies of 100-108 GHz,and input frequency which is fixed at 50-54 GHz.The microstrip frequency doubler with a DC bias filter has simulated conversion loss of 6dB-9dB with 12 dBm input power.The test result shows significant improvement compared with previously reported microstrip frequency doublers’ results.更多还原
