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 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.
