Shibin Varghese

Part Number: TRF7970A

Hi Team,
I am using TRF7970ARHBT in one of my projects.
I need a peer to peer communication.
Does TI have any reference designs for the same?.
I want an antenna which is flexible type. What are the design critierias for the antenna?.

Hi UD,
Thank you for your quick reply.
I found a reference design for TRF7970ARHBT in the below link.

Will this circuit work fine for my peer-to-peer communication application?.

Yes, this reference design for the TRF7970A can be used for peer to peer, reader writer and card emulation mode.
