摘要
针对超宽带(1~5 GHz)20 W功率放大器的设计要求,使用了一种可行的实现方法,即采用小信号S参数法对两个Triquint公司的TGF2023-02管芯进行宽带匹配电路设计,并制作了一款宽带功率放大器。测试结果表明,带内增益>10 dB,饱和功率输出20 W,测试数据与仿真结果吻合,验证了此方法的有效性。
Concerning the design goal of a wideband power amplifier working across 1 -5 GHz,this paper pro-poses an available design metliodology ： To select tlie optimal input and output impedance base on rameter ,and realize broadband matching. Based on the methodology,using twoGaN HEMTTriquint,simulation is performed and produced. The measurement results indicate that within 1 ？5 GHz,DeliveredPower is higher than 20W and the small signal gain is higher than 10 dB. Hence,the method
