分析了二极管倍频器的工作原理,提出了W波段微带二倍频器的结构。利用ADS中的谐波平衡仿真对二极管进行谐波负载牵引,得到了二极管的最佳的输出阻抗,然后进行阻抗匹配。然后在HFSS中仿真了U波段和W波段的对极鳍线过渡及输入低通滤波器。最后利用ADS对设计的倍频器进行优化。仿真结果表明,在14dBm输入功率下,输出二次谐波功率最高可达6.3dBm,三次谐波抑制达到30dB以上,该倍频器表现出了较低的倍频损耗和很高的谐波抑制。
The working principle of the diode multiplier is analyzed and the structure of the W band microstrip doubler is proposed. Harmonic balance simulation using ADS Harmonic load on the diode traction, get the best diode output impedance, and then impedance matching. In the HFSS, the transition of the femto-fin transitions and the input low-pass filter in the U-band and the W-band are simulated. Finally, use ADS to optimize the designed doubler. The simulation results show that under the input power of 14dBm, the output power of the second harmonic reaches up to 6.3dBm and the third harmonic suppression reaches above 30dB. The frequency multiplier shows lower multiplication loss and high harmonic rejection .
