摘　　要：氮化镓技术的发展为拓宽雷达的可用范围提供了可能。介绍了一种用于有源电子扫描阵列(AESA)雷达的放大器。出于设计目的,首先采用改进的Steve Cripps设计方法对功率放大器进行阻抗设计,然后给出参考的硬件设计方法,最后进行时域和频域模拟。实验结果表明,所开发的放大器在9.5 GHz、最大效率为57%的情况下,实现了超过9 W的输出功率,并且在9~10 GHz的频率范围内实现了小信号增益大于11 dB。The development of GaN technology has provided the possibility to broaden the available range of radar.An amplifier for active electronic scanning array(AESA)radar is introduced.For design purposes,the improved Steve Cripps design method is first used to design the impedance of the power amplifier,then a reference hardware design method is given,and finally the time-domain and the frequency-domain simulations are performed.The experimental results show that the developed amplifier achieved an output power of over 9 W at a maximum efficiency of 57%in 9.5 GHz,and the small signal gain is over 11 dB in the frequency range of 9~10 GHz.
