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.
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 efficien cyisbetterthan16%overthefrequencyrangefrom214to226GHzwithpumpingpowerof46.4~164mWatthe indoor temperature. A peak output power of 32mW at 218 GHz with an input power of 161 mW and several fre quency points with efficiency high than 20% are realized. This doubler can act as the pumping stage of the 660 GHz multiplier chain.
