Mouser adds Semtech’s LoRa transceivers for LPWAN and IoT applications

Continuing its new product introduction (NPI) mission, Mouser Electronics has added the SX1261 and SX1262 LoRa transceivers from Semtech.

Designed for extended battery life, the SX126x transceivers have just 4.2mA of active receive current consumption. The sub-GHz radio transceivers are suitable for long-range RF wireless applications and are fully compliant with the physical layer requirements of the LoRaWAN specification released by the LoRa Alliance.

The Semtech SX1261x transceivers support LoRa modulation for low power wide-area network (LPWAN) applications, as well as (G)FSK/MSK modulation for legacy applications. They include a new spreading factor of SF5 for dense networks, adds Mouser. The SX1261 can transmit up to +15dBm, and the SX1262 can transmit up to +22dBm with efficient, integrated power amplifiers.

The SX126x devices expand network coverage while reducing the receive-mode power consumption to just 4.5mA, this is 50 per cent less than the previous generation, notes Mouser. This extends the battery life of the LoRa-based sensors by up to 30 per cent. It also opens up many new uses for improved connectivity with IoT sensor applications.

The SX126x offer global continuous frequency coverage from 150 to 960MHz, covering all major sub-GHz ISM bands. Both radio devices are suitable for systems targeting compliance with radio regulations including, but not limited to, ETSI EN 300 220, FCC CFR 47 Part 15, China regulatory requirements, and the Japanese ARIB T-108. The SX1262 transceiver is supported by the SX1262DVK1CAS Development Kit, also available from Mouser.

Semtech’s SX1261 and SX1262 LoRa transceivers are now available in a compact 4.0 x 4.0mm package that is 45 per cent smaller than the current generation. Target applications are IoT and wireless projects, including smart meters, agricultural sensors, asset tracking, building automation, streetlights, safety and security sensors, healthcare, and robotics.
