摘要：

In this paper, the photonic bandgap, the predistortion, and the secondary harmonic tuning are simultaneously employed in feedforward amplifier to maximize the power added efficiency (PAE) and the operating bandwidth for in IMT-2000 band. In this case, the secondary harmonic tuning and the predistortion linearizer can cancel the second and the third harmonics, respectively. The PBG prevented any more harmonics to appear over 6 GHz. The feedforward amplifier was improved 4%, and 15 dBc in the PAE and the IMD(Intermodulation Distortion), respectively. The operation bandwidth was achieved twice wider than the conventional feedforward amplifier.
