Semtech Corporation, a supplier of analogue and mixed-signal semiconductors, has expanded its RFIC transceiver platform with the launch of the new SX1235, a fully integrated, high-performance, low current sub-GHz RF transceiver that provides ETSI category 1 compliance with 6 dB regulatory margin.
ETSI category 1 compliance is the highest transceiver rating for European regulations and is required for safety-critical wireless applications such as social alarms and healthcare monitoring. The SX1235 expands the target applications for Semtech’s wireless platform and provides an affordable high-performance radio IC solution to monitor, serve and increase the safety of a rising aging population.
Previous category 1 solutions have only been realisable with large and expensive discrete solutions which are difficult to design and offer little flexibility, and limiting the overall deployment of products designed to provide safety to the elderly and workers in hazardous conditions. An integrated solution with the SX1235 reduces the development time and cost with flexibility to tailor multiple products leading to the expansion of products to serve this important market segment.
With a 9.3 mA receive mode current consumption, the SX1235 is suited for category 1 applications seeking the lowest consumption possible for maximum battery lifetime while giving the highest margin to the regulatory limits. Current consumption or power efficiency in both transmit and receive modes, determines the capacity of primary or secondary back-up battery cells used in category 1 products which have a significant influence on the cost of these systems.
“The SX1235’s high performance and low current consumption confirm Semtech’s position as a world leader in the field of low power transceivers with the most robust performance,“ said Hardy Schmidbauer, Semtech’s Director of Wireless ISM Products. “With half the receiver consumption of competing devices, this technology allows reliable category 1 compliance in battery powered applications enabling miniaturized low power category 1 devices that were previously unattainable.”
