Semtech Extends Long Range Wireless Platform With Industry’s First Fully Integrated +27dBm Transceiver

Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today introduced the SX1238 to its long range transceiver platform. The SX1238 is the first device available to fully integrate transceiver and front-end module into a single package creating an ideal solution for smart metering applications such as water, gas and electric meters targeting WMBus, 802.15.4g, WiSUN, and Zigbee NAN. The SX1238 is an ideal complement to Semtech’s long range LoRa™ technology which has positioned Semtech as leader for machine-to-machine (M2M) and internet of things (IoT) solutions and infrastructure.

The highest output power available in most integrated transceivers is +20dBm or 100mW. In most smart metering solutions, manufacturers will include a separate front-end module (FEM) to boost the output power and increase the range and performance of the solution. The SX1238 is the first device to fully integrate the FEM and transceiver into a single package optimizing size and performance. Output power of +27dBm is typically viewed as the optimal tradeoff between range and battery lifetime. Most applications targeting long range and battery operation such as water and gas meters utilize +27dBm transmit or output power.

The SX1238 supports GFSK, FSK, GMSK and OOK modulation and is designed to support WMBus, IEEE 802.15.4g (SUN), WiSUN, Zigbee NAN, FCC 15.247, EN 300-220 as well as other worldwide RF standards and regulations.

“Delivering the longest range and the most robust link performance for the lowest power is the key focus for Semtech’s Wireless Product Line. The SX1238 reinforces this position by delivering an integrated solution with optimal range and battery lifetime tradeoffs,” said Hardy Schmidbauer, Semtech Director of Wireless Products.

Key Features of the SX1238

  • +27 dBm maximum output power
  • -124 dBm sensitivity @ 1.2kbps GFSK

Pricing and Availability

The SX1238 (order code: SX1238IMLTRT) is available immediately in production quantities and is priced at $2.20 each in 10,000-piece lots. Semtech offers comprehensive design assistance, including field- and factory-based support. Data sheets, volume pricing, and delivery quotes, as well as evaluation kits and samples, are available at www.semtech.com/info.

IoT & Smart Cities Stories
The challenges of aggregating data from consumer-oriented devices, such as wearable technologies and smart thermostats, are fairly well-understood. However, there are a new set of challenges for IoT devices that generate megabytes or gigabytes of data per second. Certainly, the infrastructure will have to change, as those volumes of data will likely overwhelm the available bandwidth for aggregating the data into a central repository.

Cell networks have the advantage of long-range communications, reaching an estimated 90% of the world. But cell networks such as 2G, 3G and LTE consume lots of power and were designed for connecting people. They are not optimized for low- or battery-powered devices or for IoT applications with infrequently transmitted data. Cell IoT modules that support narrow-band IoT and 4G cell networks will enable cell connectivity, device management, and app enablement for low-power wide-area network IoT. B...

When talking IoT we often focus on the devices, the sensors, the hardware itself. The new smart appliances, the new smart or self-driving cars (which are amalgamations of many ‘things'). When we are looking at the world of IoT, we should take a step back, look at the big picture. What value are these devices providing. IoT is not about the devices, its about the data consumed and generated. The devices are tools, mechanisms, conduits. This paper discusses the considerations when dealing with the...
