Go to http://www.digikey.com and search for this part number: TKS5437CT-ND

This is DigiKey's part number for a Toko Helical filter. They have a
pdf datasheet as well. It's listed at $20.90 on line in single
quantities. It is centered at 915 MHz and has a bandwidth of 25 MHz (so
it will pass from 902.5 to 927.5 and will obviously go down to 902 and
up to 928 with minimal loss). This is with an insertion loss of 2.5 dB
and a passband ripple of 1 dB.

If I wanted to make a RF bandpass filter that passed 902-928Mhz and rejected
all else how would I go about that?
