Design of a Broadband High-Efficiency Power Amplifier Based on a Miniaturized Three-Coupled Line Structure
The extended continuous inverse Class-GF mode with a large available impedance space is employed in the design of the multioctave power amplifier (PA) presented in this paper. A novel miniaturized three-coupled line structure is combined with the extended continuous inverse Class-GF mode to achieve ultra-wideband high-efficiency PAs. The novel miniaturized three-coupled line structure is analyzed in detail to meet the design requirements. To verify the effectiveness of the proposed method, a PA working in 0.7–3.0 GHz with a relative bandwidth of 124.3% is designed and fabricated by using CGH40010F. Measurements demonstrate that the output power is from 39.8 to 42.3 dBm, the drain efficiency is between 63.2% and 73.1%, the power added efficiency is from 60.4% to 71.3%, and the gain is from 9.7 to 12.3 dB. The designed PA achieves wide bandwidth and high efficiency while effectively reducing size to facilitate integration.
