SAW, CERAMIC filters question?

[houman]

Is there anyone here that have some good info about SAW filters, Ceramic filters or other kind of filters that is comparable in size.

Insertion Loss is not that important in this matter, only a high Q filter.
The band is quite narrow <1%. used in 2-3 GHz.

I need some suggestions on reading material for designing ceramic etc. or maybe some tips on simulating with ADS or HFSS.

I will appriatiate any kind of help

The SAW filters uses very special and hard to find materials , some ones are chemists compound made specyficaly to this porpouse.
I think that is very dificult made any filter without a high level chemistry laboratory.
The filters used in wifi are in the net (https://www.qsl.net/dk1ag/saw_lit.html)

I am mostly interested in ceramic actually. I am only going to do simulations and so on. Are there any alternatives as well?

You are going to have trouble with such a narrow bandwidth and high center frequency. Manufacturing tolerances will be a problem. So will temperature sensitivity.

Can you do your filtering at a lower frequency as in superheterodyne topologies?
