Transformer for a MAX2981

Hello,
I have recently started a design with a MAX2981 analog front end chip. This specific chip is an analog front end for power line communication. Within the example circuitry found here (page 12) the schematic calls for a 1:1 secondary tapped transformer. Upon searching digikey & mouser, I could find no such transformer. Could someone please point me in the right direction? I must be missing something.

Edit: I also have tried emailing maxim for a recommended part. They apparently feel like ignoring me, since I wont be selling millions of these.

Did you understand the required transformer specifications according to the HomePlug PLC standard? It's essentially a RF transformer with flat response in 2 to 25 MHz range. There is a large choice of suitable transformers avaliable from manufacturers like Coilcraft or MiniCircuits.

No idea why Maxim doesn't suggest suitable transformers. May be there's a supplemental application note or reference design?
