more details
- A resonator cannot replace a filter because the filter has multiple resonances to extend the bandwidth.
For AM carrier modulation using a narrow band resonator with 0.5% tolerance of 6MHz or +/-30 kHz the Q of 10k and it's narrow -3dB BW can as high as a crystal resonator but > 100 worse tolerance but 10% to 30% of the cost of crystal resonators.- A Ceramic filter is a double-tuned resonator so it has steep skirts but a wider BW. You need about 300 kHz BW or +/-150k unless operating at a lower data rate than max.
- The data sheet for this part is seriously lacking any specs for signal quality for signal SNR and filter distortion. It is also obsolete with the newer replacement being the towards a higher frequency range and with 100kHz step bands. Ceramic resonators in this low-frequency range are largely going obsolete also.

- I don't know what the 20 dB should be, but the inexpensive ceramic filter is the desired solution if you can find it with the right characteristics.
- Discrete filters are hard to make. unless the very high order and using NP0 caps.
