The LT Series transceiver is ideal for the low-cost, bi-directional wireless transfer of serial data, control, and command information in the favorable 260 to 470MHz band. Thanks to an advanced, synthesized architecture, this RF transceiver can form a reliable wireless link capable of transferring data at rates of up to 10,000bps over distances of up to 3,000 feet.

The LT Series is a single channel On-Off Key (OOK) RF transceiver only. There is no processor or protocol embedded inside the module, so no configuration or programming is required. This transceiver module is just the radio, so all protocol functions are handled outside the module. This allows the designer to create a system that is specifically tuned for the application, with no extra overhead, power consumption or cost above what is absolutely necessary.

The wireless transceiver is capable of generating +10dBm into a 50-ohm load and achieves an outstanding typical sensitivity of –112dBm. The wireless modules operate over a 2.1 to 3.6VDC range and feature very low power consumption, a wide operational temperature range, adjustable transmitter power, and RSSI output. As with all Linx RF wireless modules, no external RF components are required (except an antenna), which allows rapid integration, even by engineers without previous RF wireless design experience.

The LT Series wireless transceivers are compatible with the LR Series transmitter and receiver, so mixed systems are possible. This allows for systems with transmit-only or receive-only devices to use the lower cost LR Series while more complicated base-stations use the transceiver.

These RoHS-compliant modules are housed in a tiny SMD package that are well-suited to both prototyping and high-volume production.

Benefits

  • Attain longer range: send and receive digital data from up to 3,000 feet (914 meters) away when used with another LT Series wireless transceiver or LR Series module
  • Integrate with ease: simple hardware configuration lets you transfer raw data without protocol constraints or the need for user programming
  • Save power: low current consumption compared to competing wireless modules extends battery life
  • Simplify design: modules and antennas are the only RF components you need to make your product wireless; no tuning required
  • Streamline production: save time and money with wireless modules that are already tested
