Dear All:
Now I will design a filter ( HPF) , the Cutoff Frequency is about 3.69MHZ
and the 3.69MHz to 1MHz , we need about 60db to 70dbc . and We need
the signal pass the Band will we 70db performance . what's strcutr is better ?

Thanks
 

What is your max signal frequency?
 

Many tools can solve the problem.
such as filter synthesis in @nsoft designer or @DS.
With these tools you can get the prototype circuit quickly.
 

My max signal is about 30MHz ..
 

You can get a free filter program from here **broken link removed**

You can cut and try the number of elements and the look at the response graph to determine if it meets your needs.
 

Do you know any problem or tools can fit the active Filter , Like Salley-key FIlter or Gm-C filter taht can calculate the C or R Or Gm , That we just focus on amplifer design , Thanks
 

https://nuhertz.com/ has several free and trial filter programs you can use. The trial period is something like 20 days so plan ahead and load it just before you plan to use it.
