External anti-aliasing filter at ~1.3MHz

[JE]

I am looking for an anti-aliasing filter at ~1.3MHz. It should not affect signals up to 1.1MHz, but filter everything above 2.5MHz. Any recommendations regarding supplier and product?

You may want to try www.minicircuits.com for a list of available inline BNC filters. I believe they have one lowpass filter around 1.8 - 2.0 MHz.

Good Luck,

Michael

Thanks for your advice. I already tried that filter. The response doesn't drop off fast enough for our application.
