RF transmitter and Receiver modules are available in chip which can be effectively embedded with engineering projects.
These devices are simple pass-through integrated circuits. Meaning, you set up your baud-rate (as long as its within an acceptable range of whatever pair of devices you are using), and then start sending bytes to the transmitter. Quite simply, it just sends your data out the transmitter and the receiver grabs it, acting as if you had a wired serial connection between them, minus the wire! The following PIN diagram shows the details of TLP 434,434A, 916A chips. The input/output units, antennas are integrated in this chip.
