PCB specification

i want to make filter on PCB board since there is no duriod substrate available,pls any buddy tell me the epsr=?,thickness?

Hi,

Use Rogers PCB material for better quality and lower losses.

Do you mean general purpose board or you want to get a PCB done. It depends a lot on the frequency you are trying to use,

hi,i want to design band pass filter on it,at 2 ghz,will that right or the result will be unaccurate pls giude me

Are you concerned with the inband insertion loss? If you are not, probably you can try using FR4 (Er=4.6). Try to design for higher orders than the minimal to achieve your out-band rejection.

hi,any one using filter concern with inband insertion loss to be flat in pass band,can pcb board used in that field

Of course, printed filter could be used with good insertion loss flatness. If you could afford, try to design with larger bandwidth than your requirement. The flatness of the filter tends to be flatter in small band centering the centre operating frequency.

hi guys all i want is the specification standard of pcb board and which one good for rf design
