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.
