LR Series Long Range Wireless Communication Modules

The LR Series 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 5-10 times improvement in range over previous solutions. The transmitter's synthesized architecture minimizes the effects of antenna loading, providing a more stable, consistent performance. When paired, a reliable wireless link is formed, capable of transferring data at rates of up to 10,000bps over distances of up to 3000 feet. Applications operating at short distances, or lower data rates will also benefit from increased link reliability and superior noise immunity. Housed in tiny reflow-compatible SMD packages, the LR Series modules are footprint compatible with the popular LC Series (the transmitter pin-out is slightly different), 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.
