Hi all,
I am a new comer,and i do not know how to design diplexers.
pls help me.
thanks a lot!
 

diplexer is simply two band pass filters sharing the same input and have two differnt output for the two bands

so u need to know the bands u want to work in , and then begin to design the two filters

do u want to implement the diplexer using LTCC technology or what u will use
