rf bandpass filters 2.4GHz
wrote in message oups.com... 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 +- 10Mhz, -5db at +-15Mhz, -20dB +- 20Mhz. 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. Can't you do this at IF? Tam |
