Re: LC,Ceramic,SAW

You can try to recieve this information from sites of manufactures:
1.(Sawtek):www.triquint.com/company/divisions/sawtek/saw_tech_support.cfm
2. (Epcos):www.epcos.com
3. (Murata):www.murata.com
Attention! If you need in RF-pulse applications - exactly check dates of triple-transit response!

Best regards....

Re: LC,Ceramic,SAW

Ceramic types are loaded transmission lines. This makes them smaller. They have one line per pole in the filter. This limits them to about 6 poles.

SAW types are convolution types and can have many poles equivalent in a small package and also have low differential delay distortion. The disadvantage is the high insertion loss.
