中文摘要：

为获得更高的功率附加效率,采用了E类峰值放大器代替传统反向Doherty功放中的C类峰值放大器。E类峰值放大器的负载网络由一个阻抗匹配电路和两个谐波抑制电路组成。通过分析,得出了功放的设计步骤,同时为了证明分析的有效性,设计了一个工作在1.96GHz,输出为38dBm的带E类峰值放大器的反向Doherty功放。仿真结果显示,在输出功率为38dBm时,与平衡AB类功放和传统反向Doherty功放相比,带E类峰值放大器的反向Doherty功放分别有11.5%和1.1%的功率附加效率的提升。当输出功率从24dBm到38dBm变化时,测得的二次和三次谐波抑制分别大于36dB和30dB。

英文摘要：

The class-E amplifier is used as peaking amplifier in place of class-C amplifier in traditional inverted Doherty amplifier to obtain higher power-added efficiency.The load network of class-E peaking amplifier consists of one impedance matching circuit and two harmonic suppression circuits.By analyzing,the design procedure is derived,and to validate the analysis,a 38dBm inverted Doherty amplifier with class-E peaking amplifier was designed and fabricated at 1.96 GHz.The simulation results show that 11.5% and 1.1% power-added efficiency improvement is obtained in comparison with balanced class-AB amplifier and traditional inverted Doherty amplifier at an output power of 38dBm respectively.The second and third harmonic suppressions were measured to be more than 36dB and 30dB,respectively,at output power ranges from 24dBm to 38dBm.
