circuit for Bandpass filter

does anyone know where i can find a circuit for Bandpass filter? freq range 2.3G-2.5GHz bw 200MHz

Hi,

what specification of this filter that you want?
what implementation you want it: cavity, lumped, transmision line?

David

well there's many implementations depending on your specs and applications
like coupled lines capacitive gaps zigzag filters hairpin resonators filter
and comblines

read pozar and mathaei for background also microstrip filter jia sheng hond and lancaster

or if you need a fast design try the ADS design guides

You can find them on digikey!

Hi,

There's a good literature from Microwave Engineering 2nd Ed written by David Pozar.
You can refer to chapter 8 for more example. I alway preferred the coupled line design approach but you can still design using lumped element with this frequency.

You can simulate and optimized the result using ADS.


Goodluck...

Get the Ansoft Designer SV2. It is students version & free. try designing different filters there.

You can find via Internet an evaluation copy of the Nuhertz Technologies software - Filter Solutions.

Use Genesys has good Filter Synthesis tools

E. Sánchez-Sinencio's notes will help u!:D
