Receiver Optical Sub-Assemblies (ROSAs)
Elite receiver optical sub-assemblies (ROSAs) are engineered based on patented Semtech Rchip technology. Our complete line of PIN and APD ROSA products spans 1310nm nanometer (nm) to 1550nm including limiting, linear and automatic gain control (AGC) functionality. Semtech PIN ROSAs operate at +3.3V±10% and from -40°C to 85°C, with highly accurate RSSI functionality and industry best dynamic range. The ROSA products feature patented Rchip packaging in a fully compliant SC or LC type optical subassembly and are available with optional flex circuits.

Solar panels get all the attention. But in a modern utility-scale solar installation, it is the trackers, inverters and cleaning robots that determine whether a farm meets its energy production targets. Trackers keep panels correctly oriented toward the sun, inverters convert what those panels produce into grid-usable AC power, and cleaning robots keep panel surfaces free of the dust and debris that silently erode energy yield between maintenance cycles. Between them, these three asset classes account for the majority of performance variability as well as costly failures.

Decision-makers evaluating linear pluggable optics (LPO) want numbers, not abstractions. If you're new to LPO, start with Blog 1: What Is Linear Pluggable Optics?, then come back here for the key quantitative parameters for 200G LPO deployment: power consumption by module type, optical reach, electrical loss tolerance, and host port calibration requirements.

Linear pluggable optics (LPO) is one of the most significant shifts in data center optical interconnect design in a decade — but the term still causes confusion. Is it a module type? A standard? A replacement for digital signal processing function or DSP-based optics entirely? This blog answers those questions from first principles.

The USB Type-C connector has become the universal interface of modern electronics. From laptops and smartphones to Artificial Intelligence (AI) computing platforms and industrial edge devices, USB Type-C supports both high-speed data transfer and high-wattage power delivery through a single cable. With the adoption of USB Power Delivery (USB PD) 3.1 and its Extended Power Range (EPR), (Table 1) VBUS line voltages have scaled from the familiar 20V/100W standard power range to 28V, 36V and 48V — enabling power delivery of up to 240W over a USB-C cable.

France's municipalities are moving from pilot projects to full-scale Internet of Things (IoT) deployments and REX TCD Retours d'Expérience – Territoires Connectés et Durables (REX Connected and Sustainable Territories) has become the annual proving ground where that shift gets measured. Olivier Beaujard, Senior Director of the LoRa® Ecosystem at Semtech and Chair of the Board at the LoRa Alliance® attended the 3rd edition of REX TCD, held on June 16–17, 2026, at the Salons de l'Aveyron in Paris. Here’s what the event revealed about the state of connected territory development in France, and why LoRaWAN® is increasingly at the center of it.

Asia has long been recognized as one of the most dynamic regions for Internet of Things (IoT) adoption, and theAsia Tech x Singapore 2026 (ATxSG) expo made that reality impossible to ignore. Semtech and the LoRa Alliance® brought their full ecosystem to the event, and the reception was everything the team had hoped for.
Offering a rich representation of gateway manufacturers and end-node developers, the LoRa Alliance pavilion drew consistent foot traffic, meaningful technical conversations and at least one landmark business moment that signals just how far LoRaWAN® has come in the Asia-Pacific region.
Here is a look back at everything that made ATxSG a milestone event for the LoRaWAN community.
