Frequency Doubler Based Outphasing System for Millimeter Wave Vector Signal Generation
Bibliographic record
Abstract
In this paper we propose a compensation technique for millimeter wave (mm-wave) frequency doubler based outphasing system adopted to generate wideband vector modulated signals. The compensation technique utilizes multi-tone test signals to detect the system's distortions. These include the frequency doubler's unavoidable non-linearity due to the band limitation of the phase modulated outphasing signals and the gain and phase mismatch between the two outphasing signal paths. For that, an interleaved multi-tone modulated signal is used to characterize these non-idealities and synthesize a memoryless predistorter and a linear outphasing mismatch compensation filter to mitigate their effects. These blocks are subsequently applied for generating digitally modulated signals at 25 GHz with modulation bandwidths of 80 and 160 MHz with improved quality of signal.

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.
