bpf design

Up to 1GHZ we can use LC circuits to make BPF filters,but at higher freq. like as 1600MHZ how we can design BPF? please give some pdf or links or ebook names on this subject.

You can still use lumped parts, but they have to be small and you have to make sure their resonant frequencies are higher than the operating band.

You can combine lumped and distributed, like using lumped capacitors for series elements, but transmission line resonators for shunt L and C's.

And, of course, you can just use all tranmission line circuitry, which will work great at 1.6 GHz, but be a little large.

What ebook gives practical view to filter design with tranmission line?

Is there any link and software on tranmission line filter design?

Hello,


Yes, go through the following website...You will find a good filter design software...
