how to design a simple RF transmitter

Hello,

I am new to RF, can anyone suggest a quick tutorial on how to design a simple rf transmitter than can send digital signals at data rates of 50 - 100 kbps and operates up to 2-3 meters? Also this has to work in a free band or unlicesend frequency range.

If not any app notes on some cheap RF IC's to build this would be great.

Even better, does anyone know of a cheap low power rf transmitter that does the same job that I can purchase and add on to my design?

Thanks.

I think Bluetooth is appropriate for your application.
