摘要：
A saturated operation of a power amplifier with the proper harmonic tuning can be highly efficient. The harmonics, mainly the second harmonic, are generated internally by the saturation operation. Matching tolerance for the harmonic tuning is very large and can be operated across a broadband with a high efficiency. Based on the saturated amplifier, we have realized a broadband amplifier using GaN device. Across the 1.75-2.17 GHz band, the output power, drain efficiency, and gain are between 51.0-52.3 dBm, 71.0-84.4%, and 8.22-11.6 dB, respectively.
