| This paper presents a novel hybrid Class-E/FJ power amplifier (PA) that integrates Class-E/F PA and Class-J PA to formulate a high-efficiency as well as broadband performance. The theoretical relationships of the Class-E/F amplifier have been thoroughly examined, and the corresponding relationships and diagrams have been obtained. Furthermore, in the next step, theoretical analysis for Class-J has been derived, and the necessary conditions for achieving a strengthening relationship between Class-E/F and Class-J to achieve a hybrid Class-E/FJ PA have been investigated. Through the judicious configuration of parameter values, the proposed design achieves an efficiency range spanning from 61.2% to 73.4% across the 1.3-3.1 GHz. The paper delineates a systematic design process for a broadband Class-E/FJ PA based on derived theories. To validate the proposed approach, a meticulous design and fabrication process is undertaken for a 1.3-3.1 GHz broadband Class-E/FJ PA. Measurement results demonstrate that the PA can deliver a saturated output power ranging from 39.3 dBm to 42 dBm, accompanied by a gain within the 8-12 dB range. Additionally, the Power Added Efficiency (PAE) falls within the range of 58.9%-67% within the specified frequency band. A comparative analysis with similar predecessors reveals that the proposed PA outperforms others, exhibiting superior performance across a wide bandwidth. | ||
