本文介绍了一种用于毫米波集成电路的新型介质传输线--无辐射介质波导。在简要介绍了NRD波导的工作原理和工作模式后，从实验上证实了NRD波导的无辐射和低损耗特性。接下来，研究弯曲中的透射波的行为。文中还讨论了匹配终端、定向耦合器、环行器、梁式引线二极管支架和古恩二极管振荡器等典型NRD波导电路元件的结构和特性。使用这些电路元件，在35 GHz的发射机和接收机制造和它们的性能进行了评估。发射机和接收机的尺寸分别为68 mm × 66 mm和85 mm × 75 mm。发射机的输出功率为10 mW，频率温度系数为0.57 ppm/°C。接收器的温度系数也小至−0.76 ppm/°C。噪声系数为10.6 dB。该值通过在混频器中使用Si二极管获得。最后，作为NRD波导的具体应用，描述了滤波器、功率分配器和漏波天线。
This paper describes the NRD guide (nonradiative dielectric waveguide) proposed as a new type of dielectric transmission line for millimeter-wave integrated circuits. After the operation principle and the modes of the NRD guide are explained briefly, the nonradiative and low-loss nature of practical importance are confirmed experimentally. Next, the behavior of the transmitted wave in a bend is studied. Configurations and characteristics of typical NRD guide circuit elements, such as a matched terminator, a directional coupler, a circulator, a beam lead diode mount and a Gunn diode oscillator also are discussed. Using these circuit elements, a transmitter and a receiver are fabricated at 35 GHz and their performances are evaluated. The dimensions of the transmitter and the receiver are as compact as 68 mm × 66 mm and 85 mm × 75 mm in area, respectively. The output power of the transmitter is 10 mW and the temperature coefficient of the frequency is 0.57 ppm/°C. The temperature coefficient of the receiver also is as small as −0.76 ppm/°C. The noise figure is measured to be 10.6 dB. This value is obtained by using Si diodes in the mixer. Finally, as particular applications of the NRD guide, a filter, a power divider, and a leaky-wave antenna are described.
