rf bandpass filters 2.4GHz

You don't need to go custom. You need to understand the impossibility of what you are asking for. Jim

Maybe I need

Sorry I mispoke earlier. Let me restate this. Hyperlink has an 8pole filter for several of the 802.11b channels that has the mask -3db at +-

Essentially I want to keep 2.417 to 2.437 Ghz, so one of their filters centered at 802.11b, channel 4 would be ideal, except that they only sell centered at the standard channels (channel 3 and 6 are the closest), so in short I was wondering if anyone knows of a vendor that sells such a filter centered at 2.427Ghz. Thanks for any suggestions.

Hello Kevin,

That looks like you'd have to call them for a custom version which will probably be lots of $$. Or roll your own which requires a lot of RF/microwave knowledge. Or hire a consultant :-)

Problem is, if you are most likely the only one needing this there won't be an existing market and chances that any other company has the right product could be close to zilch.

Can't you do this at IF?

Perhaps you could get one of the hyperlink models and modify it.

Send your spec to these guys, they should be able to help you or at least tell you whether it can be done. I hope you can afford their products. Their tunable notch filters are very nice and might be one way of avoiding a custom design, though I don't know if they cover your frequency.
