基于分离式二极管的220 GHz 高效率倍频器
High efficiency 220 GHz frequency doubler based on discrete Schottky diodes
摘要
在分离式二极管的基础上，实现了220 GHz高效率的二倍频器结构.该倍频器的电路在450 μm宽，2.7 mm长的50 μm石英基片上实现.测试结果表明，在室温下当驱动功率在46.4~164 mW时，在214~226 GHz的频段内能够实现大于16%的倍频效率.另外，当驱动功率在161 mW时，倍频器在218 GHz频点能够输出最高功率32 mW，并且在多个频点拥有高于20%的倍频效率.实验证明，所实现的二倍频器能够作为660 GHz倍频链路的驱动前级使用.
Abstract
A high efficiency 220 GHz frequency doubler based on discrete diodes is presented in this paper. This doubler is realized with a 50 μm thick, 450 μm wide, and 2.7 mm long quartz substrate. The conversion efficiency is better than 16% over the frequency range from 214 to 226 GHz with pumping power of 46.4~164 mW at the indoor temperature. A peak output power of 32mW at 218 GHz with an input power of 161 mW, and several frequency points with efficiency high than 20% are realized. This doubler can act as the pumping stage of the 660 GHz multiplier chain.
