170-GHz transceiver with on-chip antennas in SiGe technology
Bibliographic record
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 fT/fMAXof 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 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.
