中文摘要:
      通过在300 μm厚度的GaAs衬底条件下,利用共面波导传输线实现了基波混频集成电路设计。利用半导体分析仪测试I-U和C-U曲线,并成功提取了相应的肖特基二极管模型。结合建立的肖特基二极管模型,代入Lange耦合器、中频结构和匹配网络等实现了140 GHz零中频基波混频片上电路,并加入了地-信号-地(GSG)测试封装。最终仿真结果表明:在固定中频1 GHz的条件下,变频损耗最优为-7 dB,3 dB带宽大于40 GHz。
英文摘要:
      A kind of fundamental mixer integrated circuit design under thick GaAs substrate is introduced by coplanar waveguide transmission line. The I-U and C-U curves are measured by a semiconductor, and the Schottky diode model is successfully extracted. Schottky diode is modeled and the Lange coupler, Intermediate Frequency(IF) circuit and match network are designed in zero-IF 140 GHz fundamental mixer on-chip circuit. Simulation results show that under a fixed intermediate frequency of 1 GHz, the best conversion loss is 7 dB, and 3 dB bandwidth is greater than 40 GHz.
