Ku band satellite transponder block diagram

Hi all
I need a complete satellite transponder block diagram, Ku band, but found nothing.
there are some schematics, but no one is complete. ( payload and earth station components included)
can any one help on this?
thanks

Hello there:

Why won't you try some textbooks, like JM Gomez: Satellite Broadcast Systems Engineering, Artech House, 2002?

There are dozens of good books where you can find the answers. I only doubt you can find a "complete" transponder schematic. What exactly are you trying to find?

jiripolivka, thanks for your reply

I have studied the book entitled "satellite comm..." by Maral. but have no idea about the design procedure of it yet!
my problem is with nonlinear transponder characteristic with respect to the intermodulation levels. how is it determined?
the other one: do we need an AGC and where is its situation in the block diagram?
