    摘要:

    基于电子科技大学与中国电子科技集团第十三研究所自主联合设计的肖特基二极管研制宽带360~440 GHz分谐波混频器。详细描述二极管建模,以模拟在极高频复杂电磁环境中由于二极管结构引入的相关寄生效应.在软件HFSS与ADS中,通过场与路结合的方法对分谐波混频器进行优化.实测结果显示在本振信号为210 GHz本振功率6 d Bm的驱动下,在406 GHz可得到最小变频损耗9.99 d B,在380~430 GHz范围内,变频损耗小于15 d B,在360~440 GHz范围内,变频损耗小于19 d B.

    Abstract:

    A broadband 360 ~ 440 GHz subharmonic mixer based on Schottky diode designed by UESTC and fabricated by CETC-13 is presented. Diode modeling is described to simulate the electromagnetic environment due to geometry-dependent parasitic effects in the extremely high frequency band. The whole subharmonic mixer is optimized by means of combination of field and circuit in HFSS and ADS.Measured results show that the sub-harmonic mixer yields minimum conversion loss of 9. 99 dB at 406 GHz, while the conversion loss was less than 15 dB over 380 GHz to 430 GHz and less than 19 dB over360 GHz to 440 GHz when LO power was 6 dBm at 210 GHz.
