摘要

提出了一种360 GHz高功率肖特基二极管倍频链，带宽在20 GHz以上，为3db。级联倍频器在180 GHz和354ghz的峰值效率分别为35%和23%。180 GHz倍频器在300 mW输入时产生69 mW的最大功率，而第二级倍频器在360 GHz输出时提供12 mW的输出。两种倍频器均由低寄生GaAs肖特基二极管电路组成，优化后可处理高输入功率，在最高应用功率下均不表现饱和。

A high-power Schottky diode frequency multiplier chain at 360 GHz for Gyro-TWA applications

A high-power Schottky diode frequency multiplier chain at 360 GHz, with a 3 dB bandwidth above 20 GHz is presented. The cascaded frequency doublers show peak efficiencies of 35% and 23% at 180 and 354 GHz, respectively. While the 180 GHz doubler generates a maximum power of 69 mW at 300 mW input, the second stage doubler delivers 12 mW output at 360 GHz. Both doublers consist of low parasitic GaAs Schottky diode circuits optimized to handle high input powers, and neither exhibit saturation at the highest applied power.
