摘要
研究了基于平面肖特基变容二极管的440 GHz串联式宽带二倍频器。在基波功率20 mW驱动下, 仿真显示在400~480 GHz变频损耗小于10 dB, 输出功率大于2 mW, 相对带宽18%。整个倍频器制作在一块30 μm厚的石英基片上, 无机械调谐结构, 结构简单, 便于加工。
Abstract
A 440 GHz series frequency doubler based on planar Schottky varactor diode is studied. Under the driving of the fundamental power of 20 mW, the simulation result shows that the 400-480 GHz conversion loss is less than 10 dB, the output power is greater than 2 mW, and the relative bandwidth is 18%. The whole frequency multiplier is manufactured on a 30 μm thick quartz substrate, which has no mechanical tuning structure. It is simple and convenient to manufacture.
