摘要

本设计探讨了基于Cascode f类功率放大器(PA)的可重构谐波匹配技术的分析和实现，用于支持物联网的医疗保健应用。选择特殊的电路效率和扩展的数字预失真以提供高效率和高线性特性。一种紧凑的氮化镓(GaN) F类PA被开发作为概念验证，使用可重构谐波网络来展示其宽带特性。利用可重构谐波匹配技术将增益提高到19.3 dB至饱和功率区域。并改进了共振带的操作。该设计验证了20 ~ 43dBm最大输出功率范围为74.5%，功率附加效率(PAE)为67.8%。基频平衡和次频平衡的谐波平衡从- 21dBc到- 16dBc。仿真和计算得到了验证。

A Novel Class-F Power Amplifier with reconfigurable harmonic matching technique for IoT-enabled healthcare application

This design explores the analysis and implementation to a reconfigurable harmonic matching technique with Cascode Class-F Power Amplifier (PA) for IoT-enabled healthcare application. The special circuit efficiency and extended digital pre-distortion are taken to select for providing high efficiency and high linearity properties. A compact gallium nitride (GaN) Class F PA is developed as a proof of concept, using a reconfigurable harmonic network to demonstrate its broadband characteristics. A reconfigurable harmonic matching technique is utilized to enhance the gain up to 19.3 dB to the saturation power region. and improve the resonance band operation. The design verified maximum range of output power of 20 to 43dBm at 74.5% and power added efficiency (PAE) of 67.8%. The harmonic balance of fundamental & second balance is showed from −21dBc to − 16dBc. The simulations and calculations are verified.
