本文叙述一种工作在13K、使用源电感反馈的三级砷化镓场效应晶体管放大器。在1.2-1.7千兆赫频带里,该放大器噪声温度小于10K,输入反射损耗大于15分贝。
This article describes a three-stage gallium arsenide field effect transistor amplifier operating at 13K using source inductance feedback. In the 1.2-1.7 GHz band, this amplifier has a noise temperature of less than 10K and an input reflection loss of more than 15 dB.
