I found a screenshot that I took during the prototype test. It resembles the frequency response of the NDK 10F15DG after successfully tuning the matching circuit.
The matching circuit was 3.3 uH in series and 10 pF + 5...25 pF trimmer in parallel, if I remember correctly:
I recorded the 2-port touchstone data for this filter with 1600 points. You can download it as a zip file from my Google docs: NDK10F15DG_plain.zip
