使用ADS设计放大器匹配电路--香港中文大学ADS应用笔记之一CHU Chun San, December 18, 2004 ADS Application Notes Wireless Communication Laboratory Department of Electrical and Electronic Engineering Hong Kong University of Science and Technology Impedance Matching Network Design for Amplifier to meet Gain, Input Reflection Coefficient and Stability Requirements CHU Chun San, December 18, 2004 Introduction This application note describes the procedure of designing the input matching network for amplifier to fulfill specific gain, input reflection coefficient and stability requirements. With the idea of conjugate matching, minimum signal reflection will occur at the input port of an amplifier and this will result in small reflection coefficient and larger gain. It is also important to make sure the amplifier is operating in stable region and os……
