Anthony, I suggest you consider AFC. Not enough demand for that wide a filter. Murata makes some 30 KHz 10.7 MHz filters for communication receivers.

Hi all.

I'm trying to find some 455kHz filters suitable for FM +/- some doppler. Ideally, 30kHz wide and fairly small

I have some by Murata. Types BLFYM-455C and BLFCM-455C but these are +/- 12.5k.

Any ideas? I've checked Digikey, but they only seem to list narrow band

FM

or AM filters. Is there a Murata or Toko distributor that I've missed?

Thanks

Hi David,

www.Mouser.com carries quite a few of the Murata filters including this one: CFULA455KB2A-B0 which is spec'd at +/- 15KHz @ -6dB and is US$3.92 in qty 1.

Happy New Year and 73, Tony AA2TX
