Hello everybody
I need to filter a RF signal to comply with the ETSI 300-220, for the band 868-868.6MHz.
At this limits of the band I need an attenuation about 20dB, and a band pass of -3dB 400KHz.
Therfore, I need a very selective filter.
I looked for SAW filters, but I'm not finding anything with so small band.
Any ideas about which filter technology could be the first, or any manufacturer?
I'd appreciate any help.
