Abstract
This paper presents a low-loss microstrip line (MSL), entirely fabricated using aerosol-jet printing (AJP) technology directly to a monolithic microwave integrated circuit (MMIC) chip to achieve high-speed on-chip connectivity. AJP is a direct write fabrication method capable of printing materials with viscosity ranging from 1-1000 cP, with a printing resolution and alignment precision of 10 and 2 μm, respectively. The length of the printed transmission line is 2 mm, and the S-parameters are measured from 500 MHz to 18 GHz. In this paper, the MSL is first printed on printed circuit board (PCB), and the fabrication process is optimized to reach a transmission loss of 0.3 dB/mm at 18 GHz. Subsequently, the MSL is printed atop an MMIC architecture to achieve a transmission loss under 0.9 dB/mm at 18 GHz. These results clearly show the potential of using direct printing of MSL as an alternative to conventional wire bonding for wide-bandwidth MMIC electronics packaging applications.

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
