太赫兹技术是一个新兴的交叉研究领域。在过去20年，太赫兹技术有了巨大的发展。倍频器是太赫兹差分接收机重要技术，主要运用在天文、大气和行星科学射频前端。太赫兹空白的存在主要因素是缺少高效太赫兹源和探测器。通过倍频器技术和放大技术，可以得到高稳定低相噪的倍频源。340 GHz是太赫兹大气传输窗口之一，所以340 GHz倍频源能够运用在各种通信成像系统中。肖特基二极管倍频源可以工作在常温和低温下。倍频器是倍频链路最关键的部分。通过理论分析和3D电磁仿真设计了一个340 GHz倍频器。实验得到最大输出功率为4.8 dBm，最大效率为3%，在331~354.5 GHz 输出功率大于0 dBm。实验结果证明电路仿真和建模的可行性。

Terahertz technology is a new across research field. In the last twenty years, THz technology has a great development. The multiplier was the very important aspect of the technology of terahertz heterodyne receiver front-ends in astrophysics, planetary and atmospheric sciences. THz gap exist in the application due to the lack of effective THz signal sources and detectors. Through the frequency multiple and amplification, we can get a high stability, low phase noise THz multiplier sources. 340 GHz is one of terahertz atmospheric windows, so 340 GHz multiplier source can be used in variety systems including communication and imaging system. The planar schottky diode based multiplier could work at room or low temperature. Multiplier was the most important part in terahertz multiplier chain. In this article, we have designed a 0.34 THz multiplier combined analysis of electromagnetic field theory and three-dimensional electromagnetic simulation software HFSS and ADS. The experimental results show that the max output is about 4.8 dBm, the max efficiency was 3%, in 331- 354.5 GHz, and the output power was above 0 dBm. The results proved the correctness of the diode model and simulation.
