| Abstract: | A 320-356GHz fixed-tuned frequency doubler is realized with discrete Schottky diodes mounted on 50μm thick quartz substrate.Influence of circuit channel width and thermal dissipation of the diode junctions are discussed for high multiplying effficiency.The doubler circuit is flip-chip mounted on gold electroplated oxygenfree copper film for grounding of RF and DC signals,and better thermal transportation.The whole multiplying circuit is optimized and established in Computer simulation technology (CST) suite.The highest measured multiplying efficiency is 8.0％ and its output power is 5.4mW at 328GHz.The measured typical output power is 4.0mW in 320-356GHz. |
