A 1960 semiconductor company found a second life in LoRa: the history of Semtech

Semtech was founded in 1960 in Southern California and built a business around analogue and mixed-signal semiconductor products.

For decades the company supplied power-management, protection, interface and signal-integrity technologies before becoming widely associated with a low-power wireless technology called LoRa.

The early business looks very different from the company visible today. Following the milestones in order shows which decisions changed Semtech’s direction and which capabilities remained constant.

Analogue components created a long-lived industrial foundation

Semtech developed semiconductor products used to manage power, protect circuits and move signals across communications and industrial systems.

In semiconductor and electronics markets, this kind of capability compounds over time. Manufacturing know-how, yields, supplier relationships and process experience are difficult to recreate quickly, so each generation can strengthen the next.

LoRa turned long-range low-power radio into a platform

Semtech acquired the technology that became LoRa and developed chipsets for devices needing long-range connectivity with very low power consumption.

The transaction mattered because it changed the shape of Semtech rather than simply adding revenue. It brought additional technology, customers, geographic reach or operating capability into the group and influenced the next stage of its strategy.

LoRaWAN built an ecosystem around unlicensed spectrum

An industry alliance standardised networking above the LoRa physical layer, helping the technology spread into smart metering, asset tracking and industrial IoT.

Infrastructure businesses are judged by reliability, scale and the cost of moving information. This milestone increased the company’s relevance as digital services became more distributed and more dependent on high-capacity connections.

Sierra Wireless transformed the company into a larger IoT supplier

Semtech completed its acquisition of Sierra Wireless in 2023, adding cellular modules, routers and cloud connectivity services.

This shift also changed how customers consumed the technology. Instead of treating software or infrastructure as a one-off purchase, the relationship became more continuous, with updates, capacity and services delivered over time.

How an old chip company became part of the Internet of Things

As of 18 September 2026, semtech now combines analogue semiconductors, LoRa wireless technology and cellular IoT connectivity.

The company’s current position is therefore the result of accumulated technical and commercial choices rather than one breakthrough product. That is the context future coverage should preserve.
