LT Series Long Range Transceiver Modules

The LT Series transceiver is ideal for the bidirectional wireless transfer of serial data, control, or command information in the favorable 260-470MHz band. The transceiver is capable of generating +10dBm into a 50-ohm load and achieves an outstanding typical sensitivity of -112dBm. Its advanced synthesized architecture delivers outstanding stability and frequency accuracy, and minimizes the effects of antenna pulling. When paired, the transceivers form a reliable wireless link that is capable of transferring data at rates of up to 10,000bps over distances of up to 3000 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 transceiver requires no external RF components except an antenna, which greatly simplifies integration and lowers assembly costs.
