I am using that but ... I can't even set my filter order ...
When I choose a low-pass filter I can set the filter order easily but for a band-pass filter, it doesn't work...
so I have 2 problems now!
1- I can't set filter order using Filter Design Guide (N=5, e-r,bans-pass)
2- then attenuation
If you give the known specifications for your filter, we can possibly clarify how far the remaining parameters are already determined by it. Or implement a design example.
Now, I'm trying to design it using "Passive Circuit DG - Microstrip Circuits" feature of ADS...when click the "design "it shows the following warning ..how can I modify it?
5 dB ripple is quite high, that's true. It involves particularly a high Q of individual LC sections and respective sensitivity against parameter variations, also possibly extreme L and C values.
I don't know if it's an exercise or a real hardware design problem.
