hi all
I'm going to design a microstrip bandpass filter using microwave office software.the filter pass band is:9525~9625 MHz.would you please tell me that which filter type is approperiate for my job?
for example?hairpin?interdigital?
thanks in advance

a straight parallel coupled line filter with half wave resonantors will probably be the best. You will probably figure out that the substrate dielectric constant tolerance is very wide, so you will need a wider filter band.
It might be dictated by the real estate you have to work with. If you need
to make it Small as can be you might use 0402 L's&C's.
If you have access to Genesis they have a nice Filter tool kit (M-Filter). But @ 960MHz you will
need a fairly big board area. Or a high dielectric.
what is your other requirements? Such as insertion loss, group delay, max power rating, et.
