Abstract

Abstract

The integration of satellite communication and ground mobile communication in a complementary manner has emerged as a prevailing trend, which means the wireless radio frequency front-end with Power Amplifier (PA) as the core need to tackle the dual challenges of high efficiency and large bandwidth. In this paper, the proposed input harmonic phase control method effectively overcomes the bottleneck of mutual restriction between bandwidth and efficiency. By employing a continuous inverse Class-F operating mode, it enables the reconstruction of transistor drain waveform through precise control of the input second harmonic phase. This approach ensures high efficiency, while significantly enhancing the impedance design space. Based on the expanded design space, a continuous inverse Class-F PA is designed and fabricated over the frequency band of 1.7～3.0 GHz. Experimental results demonstrate an output power of 40.62～42.78 dBm, accompanied by a drain efficiency ranging from 72.2% to 78.6%. Additionally, the gain of the designed PA ranges from 10.6 dB to 14.8 dB.
