Another filter update. I acquired a couple of monolithic crystal filters with the smaller D-151-D multi-pole package that fits the 1 x 1 SLIM modules. Most of the filters were manufactured by NDK with the exception of a single Hy-Q10726.
They are all 8-pole filters but their centre frequency varies. I now have
has a centre frequency 10.7 MHz and a 6 dB bandwidth of 15 kHz
has a centre frequency of 11.5 MHz and a 6 dB bandwidth of 30 kHz
has a centre frequency of 11.4 MHz and a ? dB bandwidth of 1 kHz
has a centre frequency of 10.7 MHz and a 3 dB bandwidth of 7.5 kHz
Took a shot with my iPod, best I can do at the moment. I'm not too happy with the ripple.
Update: 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: NDK11F30D_matched.zip
