can any one suggest a layout pattern(compact) for low pass filter..at freq 1.5GHz..and equations to get the dimensions of the layout
But I think filter synthesis can be rewarding design and a lot of fun(that makes me a dork I know).
thanks for reply...(NickS and davenn)
to NickS --> elliptical filter...bandwidth is 400 MHz and high cuttoff of abt 60 dB at BW +150 MHz.

to davenn--->i tried to find the book...but its not available in net...

hey thanks for the reply........
@NickS....i need BPF....by mistake i wrote LPF...sorry for that.......i ll try with composite filter..but i doubt whether i ll be able to get -60 dB response in stopband.( i.e less than 60 dB..for wide band)..and less ripple in pass band (less than 1dB)
@davenn ....we have library...but i doubt whether i can get those books there..
