| pass band filter - RF Cafe Forums | ||||||
|
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts. amimar Post subject: pass band filter Unread postPosted: Thu Apr 21, 2005 2:58 pm Hi I m looking fr a passband filter for thr marine band 156-162 MHz can someone help me please to find SMT component Thanks Top Guest Post subject: Unread postPosted: Thu Apr 21, 2005 5:09 pm Go to the following website: http://tonnesoftware.com/. There is a program called ELSIE, that you can use to design the filter you are looking for.

You be better off designing it yourself, it would only comprise of 5 surface mount parts at best.

Have you actually tried searching on Digikey for such a part? If it's not there, you can always use Google. I found this filters site through it http://www.ana-tech.com/.

I don't know much about it, but I remember my friend telling me that the frequency that you can sample is only as good as the processor speed. I don't think they have fast enough DSPs that can sample a 100 MHz signal. Anyone can shed a light on this? Remember, I'm clueless with DSPs. Top Profile RF Burns Post subject: Unread postPosted: Wed Apr 27, 2005 2:46 pm Hi Amimar, A bandpass filter at this frequency should be relatively simple to design. Once you have designed it and calculated the L and C values you need you should check the coil craft website for the inductors www.coilcraft.com. For the capacitors, try AVX (www.avx.com). Coil craft will probably supply you with a small quantity of free inductors. Upon finding the appropriate cap from AVX you may order it online from Radio Spares (rswww.com) etc. These components are reatily available. Good luck Posted 11/12/2012 | ||||||
