一种改进LC匹配电路的Class-F射频功率放大器

A Class-F RF Power Amplifier with lmproved LC Matching Circuit

    摘要
  • 摘要: 为了改善传统F类射频功放LC输出匹配电路二阶阻抗不为零而造成的效率损害, 提出了一种更加理想的新型LC输出匹配电路.根据双极型功放的特点, 提出的新型LC输入匹配电路可以进一步提高输出效率.通过在Jazz SiGe BiCMOS 0.35μm工艺上的电路仿真设计表明, 效率可以由63%增加到73%.工作在2.4 GHz频段上的此F类功率放大器可以适用于采用非线性调制的射频发送端.

     

    Abstract: To overcome the shortcoming of non-zero 2nd resistance of traditional output matching circuitry in class-F power amplifier, an improved output matching circuitry is proposed to increase the power-added efficiency.A novel input matching circuitry is also proposed to fit the bipolar transistor's characteristic, and farther enhance the efficiency.Simulation on Jazz SiGe 0.35um BiCMOS HBT process shows remarkably improved power-added efficiency from 63% to 73%.The novel 2.4GHz class-F PA is very suitable in nonlinear-modulated RF transmitter.
