Abstract
We present a novel bandpass filter embedded in a low-temperature co-fired ceramic (LTCC) package designed for small size and robustness. Given the three-dimensional packaging capability of the LTCC substrate, the multilayer resonators are integrated into the module - eliminating the need for their discrete versions. The resonators are comprised of high Q spiral inductors that are combined with four layer parallel plate capacitors. The novel topology of placing the capacitor in the centre and two layers below the plane of the inductor allows for simultaneous area and performance optimization. The complete LTCC bandpass filter module measures only 5 mm times 5.4 mm times 0.8 mm. This version of the design utilizes discrete coupling capacitors to minimize size. The simulation results show the filter to have a centre frequency of 1.525 GHz and a bandwidth of 128 MHz. This is believed to be the smallest implementation of a LTCC bandpass filter for GPS 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
