dear roommates:
I'm going to design some microstrip λ/4 line to make an RF chock for an
amplifier design working in frequency band 900-2400 mHz.I've designed ones for some shorter B.W
but for this frequency range I think it looks wide band to some extend.do you have any Idea to help me?
thanks in advance
 

u can use dipole bowtie antenna which each pole printed on one side of substrate
 

Indeed, lambda/4 transmission line segments will be difficult over such a bandwidth :lol:

Depending on your current for the amplifier, I would use a discrete inductor or resistor for DC supply.
 

thanks for you replies
I will test your Idea. of course I could not reach the desired result using only micro strip lines
