【摘要】：为了满足340 GHz高速OOK无线通信的需求,完成了340 GHz零偏置波导检波器的设计、加工和测试。首先,在高频电磁仿真软件HFSS中对准垂直结构二极管(QVD)进行建模仿真,并结合二极管的非线性模型确定二极管的阻抗;随后设计了输入波导-微带转换以及低通滤波器等无源结构,并同时对二极管进行阻抗匹配;最后进行了检波器的加工和测试。测试结果表明该检波器的电压灵敏度在334 GHz时最佳,最大值为2 210 V/W,并且在315 GHz~357 GHz频率范围内的典型值为1 400 V/W,其对应的等效噪声功率典型值为5 p W·Hz-0.5。最后,还利用该检波器进行了340 GHz频段的高速OOK信号接收实验,结果表明,该检波器能够近乎无误地检测10 Gbps的OOK信号,并且在OOK信号速率为15 Gbps时,检波器解调得到的误码率为3.15×10~(-7),证明了该检波器的高速信号检测能力能够满足高速OOK无线通信系统的需求。
[Abstract]:In order to meet the requirement of 340 GHz high speed OOK wireless communication, the design, processing and testing of 340 GHz zero offset waveguide detector are completed. Firstly, the vertical structure diode QVD is modeled and simulated in the high frequency electromagnetic simulation software HFSS. Based on the nonlinear model of the diode, the impedance of the diode is determined, and then the passive structures such as input waveguide microstrip conversion and low pass filter are designed, and the impedance matching of the diode is carried out at the same time. Finally, the fabrication and test of the detector are carried out. The test results show that the voltage sensitivity of the detector is the best when the sensitivity of the detector is 334 GHz. The maximum value is 2 210 V / W, and the typical value in 315 GHz~357 GHz frequency range is 1 400V / W, and the corresponding equivalent noise power is 5 p W 路Hz-0.5. Finally, the high speed OOK signal receiving experiment at 340 GHz band is carried out by using the detector. The results show that, The detector can detect the OOK signal of 10 Gbps without error, and at the rate of 15 Gbps of OOK signal, The error rate of detector demodulation is 3.15 脳 10 ~ (-1) ~ (-7), which proves that the high speed signal detection ability of the detector can meet the requirement of high-speed OOK wireless communication system.
