Hello!

I have no experience working with frequencies in the gigahertz range,
but I am working on a project that broadcasts AM signals on 1030 MHZ
and 1090 MHZ. It is the frequencies that airplane transponders
communicate with ground stations on.

Does anyone have practical experience building a receiver for
frequencies in this range? And what are some good suppliers for
components at these frequencies?

I am looking for some example circuit diagrams and pcb layouts or
something like that.

Thanks for any help.
