(Invited) SiGe Applications in Automotive Radars
Bibliographic record
Abstract
An overview of the SiGe technologies used at Infineon Technologies for radar applications will be given. The production of bare-die chips started in 2009 using the bipolar technology B7HF200. Since 2012 packaged MMICs in an embedded wafer level ball grid array (eWLB) are available. Process challenges and solutions for radar chips in an eWLB package are presented. Examples of commercial SiGe radar chips in production are shown. Furthermore Infineon’s next generation BiCMOS technology B11HFC with f T of 250 GHz and f max of 370 GHz is described. In addition, significant improvements of the cut-off frequencies can be achieved by replacing the currently used double-poly self-aligned configuration by a more advanced SiGe HBT architecture like IHP’s transistor module with selective base link epitaxy. The capability of this transistor cell for future BiCMOS generations was demonstrated by integrating it into Infineon’s 130 nm CMOS process. A transistor performance with f max of 500 GHz was achieved.

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.
