A 160 GHz Pulsed Radar Transceiver in 65 nm CMOS
Bibliographic record
Abstract
This paper presents a 160 GHz center frequency pulsed 65 nm CMOS transceiver for short range radar applications. Four phased array transceivers were implemented in a single chip with antennas implemented in a BGA package. The implemented transmitter is capable of producing pulses of 100 ps widths ( >20 GHz RF bandwidth) at a 160 GHz carrier frequency. The measured effective isotropic radiated power (EIRP) is 18.8 dBm for continuous wave outputs. The analog beam forming receiver achieves an overall gain of 42.5 dB, -14 dBm IP1dB, 7 GHz bandwidth, and a noise figure of 22.5 dB. The sliding window time-dilation baseband relaxes the output data rate and subsequent digital processing requirements. Fine grained duty cycling reduces power dissipation. The entire chip consumes 2.2 W from 1.2/1.4 V supplies in a 65 nm digital CMOS process.

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.
