A Systematic Approach of Generalized Reactance Compensation Technique in Wideband Class-E Power Amplifier for Lower High Frequency (HF) Bands
Bibliographic record
Abstract
This paper discusses about systematic design approach of Reactance Compensated Class-E. The theory behind conventional Class-E is described then differences between Reactance Compensation Class-E is explained and derived. The reactance compensated Class-E gives better high efficiency bandwidth. The range of shunt capacitor value that can maintain high efficiency operation also increases compared to conventional Class-E. The overall impedance for reactance compensated Class-E is derived and shows that it is the same as Class-E. The contribution of this paper is to present a high-performance wideband Class-E Power Amplifier in the operating frequency of low MHz range for the first time. Also, a systematic design approach on the theoretical derivation of Class-E Power Amplifiers with reactance compensation method is presented in this work. To prove the efficiency and correctness of the designing method and simulation results, we fabricated and measured the proposed design. Wideband Class-E Power Amplifier at low MHz frequency is achieved. The results show that all simulation, designing methods and experimental results confirm each other. The theoretical results show that reactance compensated Class-E gives at least 17.3% and for simulated result, it shows at least 33.3% increase in high efficiency bandwidth compared to conventional Class-E. The measurement result shows the reactance compensation technique shows an increase in its high efficiency bandwidth by 52.3% compared to conventional Class-E. Reactance compensation can be used to improve the high efficiency bandwidth of conventional Class-E and shows promises in realizing wideband Class-E. As the overall impedance of reactance compensated Class-E is the same as conventional Class-E, implementing this method would simplify the analysis in other high efficiency amplifier topologies like push-pull, Doherty, and Outphasing.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
