Overview

The LAMBDA68-8S is an 868MHz LoRa transceiver module based on the Semtech LLCC68 LoRaWAN modem. This surface-mount module integrates an RF switch and an impedance matching network to provide a high-performance wireless link with a budget up to 151dB. It is designed for long-range, low-power communication in the European ISM band.

Why Choose This Part

The module offers an impressive 22dBm output power and high sensitivity of -148dBm, ensuring robust connectivity even in challenging RF environments. It simplifies design by integrating the RF switch and matching network into a compact 16-SMD package that is CE compliant for use in the 868MHz band.

Applications

Smart Metering
Reliable long-range communication for utility meters located in dense urban or basement environments.
Agriculture Sensors
Low-power telemetry for soil moisture and environmental monitoring across large outdoor areas.
Industrial IoT
Industrial communication for remote equipment monitoring and facility automation.
Smart Home Infrastructure
High-sensitivity wireless connectivity for lighting, security, and climate control systems.
