本文首次报道了基于碳纳米管（CNT）冷阴极场发射的微波（MW）倍频器的理论分析、设计和实现。利用CNT冷阴极场发射的非线性特性，利用输入信号的谐波产生场发射电流，实现倍频。我们从理论上和实验上证明，MW 电场能够从 CNT 冷阴极感应出含有谐波的电流，而直流 (dc) 电场可以有效地增加谐波的幅度。设计并制造了凹入谐振腔结构，以将所需的微波和直流电场组合传递到碳纳米管冷阴极上，并实现微波倍频器。该器件的目标二次谐波频率为 1.868 GHz，三次谐波频率为 2.802 GHz，驱动信号频率为 0.934 GHz。通过简单地增加直流偏置，成功地使目标二次谐波的幅度增加了 12.43 dB。利用这样的装置，可以获得具有MW频率谐波的直接调制电子束。该原理和设计均可在频率可调真空电子器件中得到应用。
This paper reports for the first time the theoretical analysis, design, and realization of a microwave (MW) frequency multiplier based on a field emission from carbon nanotube (CNT) cold-cathode. The nonlinear characteristic of field emission from CNT cold-cathode is utilized for generating field emission current with the harmonics of input signal and achieving frequency multiplication. We demonstrated both theoretically and experimentally that an MW electric field is capable of inducting current with harmonics from CNT cold-cathode and that a direct-current (dc) electric field can effectively increase the amplitudes of the harmonics. A reentrant resonant cavity structure was designed and fabricated to deliver the desired combined MW and dc electric fields onto CNT cold-cathode and realize the MW frequency multiplier. The device has the target second harmonic at a frequency of 1.868 GHz and a third harmonic at 2.802 GHz with a driving signal at frequency of 0.934 GHz. By simply increasing dc bias, a 12.43-dB increase of the amplitude of target second harmonic is successfully obtained. With such a device, directly modulated electron beam with MW frequency harmonics is obtained. Both the principle and the design can find applications in frequency tunable vacuum electron devices.
