阻抗匹配与史密斯(Smith)圆图
在处理RF系统的实际应用问题时,总会遇到一些非常困难的工作,对各部分级联电路的不同阻抗进行匹配就是其中之一。一般情况下,需要进行匹配的电路包括天线与低噪声放大器(LNA)之间的匹配、功率放大器输出(RFOUT)与天线之间的匹配、LNA/VCO输出与混频器输入之间的匹配。匹配的目的是为了保证信号或能量有效地从“信号源”传送到“负载”。-Impedance matching and Smith (Smith) Smith chart in dealing with the practical application of RF system, there would always encounter some very difficult work on the part of the cascade of different impedance matching circuit is one of them. Under normal circumstances, the need for matching circuits, including antennas and low noise amplifier (LNA) matching between the power amplifier output (RFOUT) match between the antenna, LNA/VCO output and mixer input match between. The purpose of matching is to ensure the effective signal or energy from the " source" sent to the " load."
