Design methodology of high efficiency continuous mode transfer power amplifiers with one octave bandwidth
Bibliographic record
Abstract
This paper discusses a methodology for design of broadband power amplifiers (PA's). In comparison to conventional class-F and inverse class-F modes, the continuous mode provides wider design space for the realization of broadband efficiency PAs through the proper termination of fundamental, second and third harmonic impedances. This manuscript presents an approach based on in-band mode transfer between continuous inverse class-F and continuous class-F to allow for the realization of high efficiency PAs with upto one octave bandwidth. The validation of this mode transfer concept is performed using a 10-W Gallium Nitride (GaN) device. The PA, which was designed in Advanced Design Systems, exhibited a drain efficiency of greater than 60%, a power gain higher than 13 dB, and an output power of more than 10W over the frequency band ranging from 460 to 920 MHz, which corresponds to one octave bandwidth or 67% of fractional bandwidth.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
