LR SERIES RECEIVER MODULE DATA GUIDE
PRELIMINARY
DESCRIPTION
The LR Receiver is ideal for the wireless
transfer of serial data, control, or command information in the favorable 260-470MHz band.

sensitivity of -112dBm, which provides a 5-10
times improvement in range over previous solutions. When paired with a compatible Linx

transmitter, a reliable wireless link is formed, capable of transferring data at rates
of up to 10,000bps at distances in excess of 3,000 feet. Applications operating at
short distances, or lower data rates will also benefit from increased link reliability
and superior noise immunity. Housed in a tiny reflow compatible SMD package,
the LR Receiver module is footprint compatible with the popular LC-S Receiver,
allowing existing users an instant path to improved range and lower cost. No
external components are required (except an antenna), allowing for easy
integration, even by engineers without previous RF experience.
FEATURES
