提出了一种采用新型集成平衡场效应管的紧凑型宽带平衡倍频器。MMIC工作在128~220 GHz的二次谐波输出频率，154 GHz最大输出功率为1.8dBm，输入功率为9dBm。由于平衡的拓扑结构，MMIC能够使用单个4指设备在整个G频段(140到220 GHz)上提供二次谐波输出功率。MMIC采用变形HEMT技术实现，栅长为35 nm，便于集成到多功能MMIC中。
A compact broadband balanced frequency doubler with a novel integrated balanced FET is presented. The MMIC operates at second harmonic output frequencies from 128 to 220GHz with a maximum output power of 1.8dBm at 154GHz and an input power of 9dBm. Due to the balanced topology the MMIC is able to provide second harmonic output power over the entire G-band (140 to 220 GHz) using only a single 4-finger device. The MMIC is realized in a metamorphic HEMT technology with 35 nm gate-length for convenient integration into multifunctional MMICs.
