摘要
无人机机载功率放大器的性能一直是限制无人机技术发展的主要因素,为此提出了将功率合成技术应用于无人机数据系统的方法解决上述问题。利用微带线技术结合系统性的电路调试方法,辅以Advanced Design System仿真软件优化设计,同时采用实频技术法进行宽带功放设计,成功研制了频段在1.3 GHz^1.7 GHz的功率放大器,单路功率放大器采用级联的技术输出功率为8 W,两路合成后,实测总输出功率为15.67 W,合成效率达97%,性能稳定,达到实用水平。
The performance of airborne power amplifier （PA） plays an important role for UAV technology development. Here in this paper specifically we propose a new PA design method based on power combining technology. By the use of mierostrip technology and systematicness circuit debugging method, we manufacture a PA which can work stably with high availability from 1.3 GHz to 1.7 GHz. Also we optimize our design through Advanced Design System （ADS） software simulation, as well as achieve wide band via real frequency technique. The single path PA can export 8 W power, while after combining two paths together, the export power can increase to 15.67 W, which means the combine efficiency reaches 97%.
