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.


They are called transponders.

You can use a generic satellite receiver to pick it up, they tune from about
950 MHz to 1450 MHz, on the cable from the LNA
The old c-band satellite dish stuff, just take off the LNA and put a good
antenna on the end of the cable, you can make one out of a 1 gallon paint
can. You can buy a low end new satellite receiver for $200, or get a used
off ebay.

The band is easy to design in, for receivers.
