Description
The LR Series transmitter is ideal for the cost-effective 
wireless transfer of serial data, control, or command 
information in the favorable 260 to 470MHz band. 
When paired with a compatible Linx receiver, a reliable 
wireless link is formed, capable of transferring serial 
data at rates of up to 10,000bps at distances of up 
to 3,000 feet (1,000m). Applications operating over 
shorter distances or at lower data rates also benefit 
from increased link reliability and superior noise immunity. The transmitter’s 
synthesized architecture delivers outstanding stability and frequency 
accuracy and minimizes the affects of antenna pulling. Housed in a tiny 
reflow-compatible SMD package, the transmitter requires no external RF 
components except an antenna, which greatly simplifies integration and 
lowers assembly costs.
