A subharmonic injection-locking scheme for LO phase shifting phased-array architectures
Bibliographic record
Abstract
A ninth subharmonic injection locking scheme is proposed for LO phase shifting based phased-array architectures operating in the ISM band at 24 GHz. The presented architecture employs a two stage phase shifter, a limiter and a Q-enhanced tuned amplifier to synthesize multiple phases of ninth-harmonic tones from a 2 GHz reference at the destination and in close proximity to the RF/mm-w injection-locked oscillators operating at 18 GHz. A digital phase shift calibration technique is also discussed. The reported LO phase shifting and synthesis scheme is implemented in IBM's 120 nm CMOS technology and consumes a total of 11.8 mW from a 1.2 V supply. The oscillator core consumes a 3.7 mW. The maximum phase shift error at 18 GHz is 4.29° and 0.42° before and after calibration, respectively.

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.
