摘要

报道了一种高功能inp基共振隧道高电子迁移率晶体管(RTHELT)的微波频率特性。基于小信号s参数测量,栅极长度为0.7-/spl mu/m的RTHEMT最大电流增益截止频率f/sub - T/为28.6 GHz,最大功率增益截止频率f/sub - max/为90 GHz。大信号特性也被报道,显示了rthemt具有高次谐波乘法和高转换效率的倍频应用潜力。

Microwave-frequency operation of resonant tunneling high electron mobility transistors
Microwave-frequency characteristics of a highly functional InP-based resonant-tunneling high electron mobility transistor (RTHELT) are reported in this paper. Based on small-signal S-parameter measurement, a maximum current gain cutoff frequency f/sub T/ of 28.6 GHz and a maximum power gain cutoff frequency f/sub max/ of 90 GHz were obtained for an RTHEMT with a 0.7-/spl mu/m gate length. Large-signal characteristics are also reported, showing the potential of RTHEMTs for frequency multiplier applications featuring high order harmonics multiplication with high conversion efficiency.
