Transmit only BLE hardware

[Amit]

Are there any nordic ICs that only have transmit capabilities? Would there be any power benefit to only supporting transmission if the application only needs to transmit (like iBeacon)?

That's a good question especially when we're talking about iBeacon type devices. I can see that there's little to be saved in the silicon costs by removing the receiver, but for battery life concerns in a transmit-only device it would be good to have the receive circuit entirely off if the device is non-connectable and non-scannable.
