摘要
微波毫米波与太赫兹噪声源主要用于产生噪声信号,是噪声系数测试系统的核心组成部分.本文对近年来国内外噪声源的发展情况进行总结,将现有的噪声源归纳为基于数字和模拟电路技术、基于固态二极管技术、基于场效应管技术、基于黑体和热电阻技术、基于光电融合技术共5类噪声源,并对这5类噪声源的主要技术特点进行了分析,同时对各类型噪声源的国内外研究现状进行了对比,并对其应用前景和发展趋势进行了展望.
Abstract
Microwave,millimeter wave and terahertz noise sources are mainly employed to generate noise signals,and they are the core components of noise figure measurement system.This paper has summarized the development of noise sources at home and abroad in recent years.The exiting noise sources are divided into five categories:based on digital and analog circuit technologies,based on semiconductor diode technology,based on field effect transistor technology,based on black body and heater circuit technologies,based on photoelectric fusion technology.The main technical characteristics of these five types of noise sources are analyzed.The research status of different noise sources are compared,and the application prospects and development trends are outlined.
