Introduction

The Atmel

®

 software development tool RF Design Kit enables the programming and setting 

of a wide range of RF automotive products to build RF systems for development purposes. 
The software is particularly suitable for setting parameters of UHF receiver and transmitter 
demo boards. 

The ATA5749, Atmel’s newest UHF transmitter, boasts many new features. The main new 
feature is its programability. Parameters such as transmit power, the transmit frequency, 
and the frequency deviation for FSK modulation can be programmed. The latest RF Design 
Kit (version 1.0.7) supports the ATAB5749, which is the demo board for the transmitter 
ATA5749. This application note provides an introductions to using the ATAB5749 with the 
RF Design Kit software.
