CAMARILLO, Calif. -- January 10, 2013

Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and
mixed-signal semiconductors, today expanded its RFIC transceiver platform with
the new SX1235, a fully integrated, high-performance, low current sub-GHz RF
transceiver that provides ETSI category 1 compliance with 6 dB regulatory

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 realizable with large and
expensive discrete solutions which are difficult to design and offer little
flexibility, thus 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 to multiple products leading to the expansion of
products to serve this important market segment.

With an industry-leading 9.3 mA receive mode current consumption, the SX1235
is ideal 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.”
