Introduction

The LR Receiver is ideal for the wireless transfer of serial data, control, or command information in the favorable 260 to 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 serial data at rates of up to 10,000bps at distances of up to 1.5 miles (2,500m). This range may be reduced depending on the regulations in the country of operation. Applications operating over shorter distances or at lower data rates also benefit from increased link reliability and superior noise immunity. Housed in a tiny reflow-compatible SMD package, no external RF components are required (except an antenna), allowing for easy integration, even for engineers without previous RF experience.
