Hi all,
I am trying to design a bandpass filter for f0 of 9.25 GHz, BW of 500 MHz. I have a somewhat suitable design which was done using a filter design wizard, however there appears to be passbands at all of the multiples of the one intended. So, passband at 9.25 GHz, 18.5 GHz, ~ 27GHZ, ~36 GHz, ~45 GHz etc.
If this is undesired, what are some measures I can do to eradicate these extra passband multiples?
I hope that is clear enough!
