Abstract
A single-chip transceiver with on-die transmit and receive antennas, Rx and Tx amplifiers, 165-GHz oscillator and static frequency divider is reported in a SiGe HBT process with f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</sub> /f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">MAX</sub> of 270 GHz/340 GHz. This marks the highest frequency transceiver in silicon and the highest level of functional integration above 100 GHz in any semiconductor technology. The downconversion gain peaks at -5 dB and the transmit power is -5 dBm when measured at the transceiver pads. Both degrade by approximately 25 dB when measured above the antennas of the transceiver with on-die antennas. The experimental performance of dipole (with and without floating metal strips) and patch antennas is also investigated. The measured 15-dB gain of a standalone amplifier is centered at 170 GHz and remains higher than 10 dB from 160 GHz to 180 GHz while the saturated output power is 0 dBm at 165 GHz.

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 it
