Abstract :
A 0.33THz frequency doubler is realized with planar Schottky diodes, and the diode is mounted on 50 μm thick quartz substrate. The complete multiplying circuit is optimized and established in 3-D electromagnetic simulation suite. The doubler is self-bias and fixed-tuned. The highest tested multiplying efficiency is 8% and its corresponding output power is 5.4mW with input power of 68mW at 328GHz. The typical measured efficiency is 6% in frequency band 320-358GHz. To the authors´ knowledge, these results are comparable to reported frequency doubler performance around 330GHz with integrated diode technology.
