A novel Schottky diode frequency doubler in E-band, using biased series-connected diodes in the output waveguide, is reported. The doubler was implemented using a GaAs Schottky Monolithic Microwave Integrated Circuit (MMIC) process with integrated capacitors and beam leads. A comparison is made with a hybrid doubler using a more conventional single-ended configuration with two discrete diodes in a planar transmission line circuit. Both devices exhibit excellent performance over the 67–78 GHz design bandwidth, with the novel MMIC design producing 25 to 55 mW at 12 to 22% power conversion efficiency. Good agreement of measurements with simulations was also found.

比较新型MMIC和混合电路高效GaAs肖特基二极管毫米波倍频器

据报道，一种新颖的E波段肖特基二极管倍频器在输出波导中使用偏置串联二极管。使用具有集成电容器和束引线的GaAs肖特基单片微波集成电路（MMIC）工艺来实现倍频器。使用混合倍增器进行比较，该倍增器使用更传统的单端配置，在平面传输线电路中具有两个分立二极管。两种器件在67–78 GHz设计带宽上均具有出色的性能，新颖的MMIC设计以12至22％的功率转换效率产生25至55 mW。还发现测量结果与模拟结果吻合良好。
