How to Design an RF Power Amplifier: Class E 链接:pan.baidu.com/s/1UWQZ35 提取码:jhf4 这里可以总结下Class D类和E类功放的异同点:D类和E类起作用的都是串联LC谐振网络,都是通过开关让LC谐振网络在电源和地之间切换(D类采用inverter实现,E类采用开关和并联电容实现)。LC网络中不会有直流功耗,焦点...

CH2 Linear Power Amplifier Design 思维导图: 2.0~2.2:功率(loadline)匹配 在电路理论中我们学过,当负载阻抗跟电源的内阻共轭(conjugate match)时,负载的有功功率最大。因此通常在匹配PA的输入阻抗时,将晶体管的输入阻抗共轭匹配到50Ω (即通常射频系统的输出阻抗)时,往往能得到更大的增益,此时对应PA的S11为0(...
