HI,
We have a piece of telecommunications equipment with a low cost 315MHz superhetrodyne RTE receiver. The receiver has a SAW filter at the input but still suffers some desensitisation from close ISM band equipment such as Wi-Fi and cordless phones.
Can anyone suggest a simple non-crytical microstrip notch filter design which could be implemented on 1.6mm FRG-4 fiberglass and cover any or all of 900MHz, 2.4GHz and 5.6GHz ISM bands.
As an old telecommunications engineer this is getting a bit out of my field.
Thanks, Phil
