摘　　要：采用反向并联肖特基二极管对设计了一种330 GHz二次谐波混频器。混频器电路采用微带结构,使用波导-微带探针耦合的形式进行过渡;采用50μm厚的石英作为基板,有效减小了电路体积;采用HFSS和ADS对电路进行仿真和谐波平衡仿真。仿真结果显示,混频器在310～350 GHz范围内的变频损耗优于9.5 dB,所需本振(LO)功率为3 dBm,有效降低了对本振的要求。A novel 330 GHz sub-harmonic mixer based on anti-parallel Schottky diode pair is proposed.Microstrip circuit is used with waveguide-microstrip probe transition.Quartz glass of 50μm thickness is adopted as the substrate,which is good for size-reduction.HFSS is utilized for 3D simulation first and then ADS for harmonic balance simulation.The simulation results show that the conversion loss is better than 9.5 dB form 310-350 GHz.The required Local Oscillator(LO)power is only 3 dBm,which reduces the demand on LO source.
