摘要：

This paper presents the development of the wideband power amplifier (PA) for application to intelligent cognitive radios. The load-tracking based on the frequency-varied load-pull technique is proposed for the PA design. The load impedance tracking is realized by filter network synthesis. A 3-7.5-GHz broadband IPA is demonstrated in 0.15-mu m InGaAs pseudomorphic HEMT technology. Operated at 3.5 V, the P-1 (dB) and power-added efficiency of the PA are better than 21.4 dBm and 20%, respectively.
