WIRELESS MADE SIMPLE
LR SERIES RECEIVER MODULE DATA GUIDE
DESCRIPTION
The LR Receiver is ideal for the wireless transfer of
serial data, control, or command information in the
favorable
260-470MHz
band.
The
receiver’s
advanced synthesized architecture achieves an
outstanding typical sensitivity of -112dBm, which
provides a 5 to 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 of up to 3,000 feet.
Applications operating over shorter distances or at
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 for engineers without previous RF experience.
