Semtech Corp. has launched two new LoRa Gen 4 transceivers that extend the capabilities of the LR2021 Gen 4 transceiver, introduced in March 2025, into cost-optimized and application-specific solutions. Joining the LR2021 are the new LR2022 dual-band and LR2012 sub-GHz LoRa transceivers.
The new devices allow customers to leverage the fourth-generation LoRa performance, while optimizing specific features and price points. “We designed the Gen 4 portfolio to give customers choice – they can select the capabilities they need without paying for features they won’t use,” said Madhu Rayabhari, senior vice president and general manager, analog mixed signal and wireless products group at Semtech, in a statement

The LR2021 is a multi-protocol transceiver that is compatible with LoRa, LoRaWAN, and fast long range communication at data rates up to 2.6 Mbits/s, making it suitable for AI-enabled IoT solutions. It also ensures compatibility with legacy devices with support for various physical layer modulations commonly used in short-range, low-power wireless protocols.
The LR2022 dual-band transceiver targets applications that require global sub-GHz, 2.4 GHz, or satellite connectivity while maintaining cost-effectiveness, while the LR2012 is tailored to sub-GHz applications, with enhanced sensitivity down to -142 dBm, making it suited for traditional IoT deployments.
The LoRa Gen 4 transceivers are reported to deliver data rates comparable to those achieved by short-range protocols, while extending LoRa capabilities with a high link budget and range, and improved resilience against environmental challenges and interference for industrial environments or extended outdoor deployments. Key applications include drone communication systems, AI-driven security cameras, battery-powered sensors for predictive maintenance, audio classification devices, and image recognition platforms.
All three devices offer enhanced LoRa and frequency shift keying radio performance, offering more efficient channel activity detection, support for multiple spreading factors, and round trip time of flight. They also maintain backward compatibility with over 450 million deployed LoRa devices.
The LR2021 is available for customer sampling, with production scheduled for October 2025. The LR2022 and LR2012 devices are scheduled for production in the first quarter of 2026 and the second quarter of 2026, respectively.
