Abstract

fetched live from OpenAlex

A binary phase-shift keying (BPSK) modulator using a microstrip ring-hybrid and HFET switches is proposed here. The fabricated BPSK modulator works from 3.2 GHz to 3.5 GHz with output amplitude balance less than 1 dB and phase balance within 2deg of ideal 180deg. Its conversion loss is around 6.7 dB and relative flat across this frequency range. Around its center frequency, the amplitude balance is less than 0.1 dB and the phase balance is almost ideal 180deg. This results in a perfect square- wave modulation spectrum with carrier suppression over 40 dB and spurious suppression over 33 dB. The fabricated modulator has better power performance than the previously-published modulators.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
