IF Filter needed
IF Filter needed
(OP)
Hi all,
I need some information.
This is the filter I am currently using:
ht tp://www.e lfa.lv/cgi -bin/index .cgi?artnr =56-956-14
It is a ceramic 455KHz filter. Insertion loss between 0 and 5 dB. Currently 3 dB down bandwidth of 10 KHz.
What I need is a 3 dB bandwidth of around 20 KHz. The center freq can be between 400 KHz to 500 KHz not much else is critical.
Can someone direct me were I can find a filter that might or will work.
Thanks

That did help. I found a few filters I went over that might work.
It's a real pain trying to find what I am looking for.
Thank you again.
If anyone else has an idea please post.
Thanks all.
