目前,在雷达研制中广泛采用砷化镓场效应管放大器作为雷达前端器件。特别是在对雷达灵敏度有较高要求时,前置放大器一定要具有低噪声、高增益、低驻波等特点。这样就要求采用计算机辅助设计技术进行放大器的设计。本文介绍了作者为警戒雷
At present, gallium arsenide FET amplifier is widely used as a front-end radar device in radar research. Especially in the high sensitivity of the radar requirements, the preamplifier must have low noise, high gain, low standing wave and so on. This requires the use of computer-aided design techniques for amplifier design. This article describes the author as Alert Ray
