Manchester coding is not really necessary.
The Nordic VLSI chips can be direcly connected a microprocessor UART.
I've used the nRF401 in several projects that way. It offers 19200 kbps 
transfer
speed at decent distances.
One project was a timing system for car races where the measuring stations 
for
start, stop and mid timing was using this module for communication with the 
main
application on a PC.
The RF modules worked as a direct replacement for the RS-485 network which
we could also use.
