I want to design a broadband filter.The passband is 1.5GHz to 13GHz.who can give me some advice or reference book?
 

The bible for all kind of filter is:
Microwave Filter, Impedance Matching networks and Coupling Structures.
This book was written by G. Matthaei, L. young and E.M. Jones.

On this book you can find all the suggestions that you need.

Have a good read.
 

Hi,
1.5GHZ to 13GHz is ver very wide. You may just use a high pass filter.
If you are using stripline also it is difficult. Just some how cutoff the LF noise.

Look at to the products coming from "guru" filters factories like K&L, Reactel etc.
In particular the "bandpass" you require is what the "guru" companies call hi-pass filter.
This means that is very difficult to get so high BW.
Practical resctritions is mainly related to the parasitic series inductance of the in line capacitors.

Your filter is a very broadband. I would suggest you build it tuneable.

You are aware that if the load sees the generator as resistive network and SO the generator sees the load as resistive network it means the filter is broadband. Please keep in mind this trick.

rainer suggested: Microwave Filter, Impedance Matching networks and Coupling Structures. by G. Matthaei, L. young and E.M. Jones.

be creative! I guess that is the best book.
