摘要
为了提高射频前端电路的效率和减少电路尺寸,本文提出了功放天线一体化设计方法。这种设计方法直接将功率放大器与天线集成,而无需任何的匹配电路,在不影响效率和输出功率的情况下,有效减少射频前端的损耗和电路尺寸。基于功放天线一体化设计方法,设计了工作在2.45 GHz的F类功率放大器和贴片天线,通过对比一体化设计与独立设计,测试结果表明在工作频率下的一体化设计比独立设计的附加效率(power added efficiency, PAE)提高了9.2%,电路尺寸减少了43.5%。
In order to improve the efficiency of the RF front-end circuit and reduce the size of the circuit,a method based on integrating the power amplifier with the antenna is proposed.This method directly integrates the power amplifier with the antenna without any matching circuit,which can reduce the loss and circuit size of the RF front-end without affecting the efficiency and output power.Based on the integrated design method of the power amplifier and the antenna,the class F-power amplifier and patch antenna working at 2.45 GHz are designed.Compared with the integrated design and the independent design,the efficiency of the integrated design under the operating frequency is increased by 9.2%,and the circuit size is reduced by 43.5%.
