Semiconductor supplier Semtech has announced the availability of the LoRa Corecell reference design for indoor gateway applications. The reference design is developed to the LoRaWAN protocol targets for home, building and factory automation.
The LoRa Corecell reference design comprises two new integrated circuits (ICs), LoRa-based gateway baseband transceiver (SX1302) and the low power multi-band Sub-GHz RF Front End (SX1250), enabling customers to deploy cost-effective indoor gateway solutions. The ICs are designed to reduce power consumption up to one tenth the power of legacy products, enabling power constrained USB-based gateways and mobile battery operated gateways. The products help reduce bill of materials (BOM) cost and provide a small package form factor while increasing performance based on a larger number of modulators and demodulators.

“The LoRa Corecell reference design’s key features, including low power, smaller package and higher integration with improved performance, aim to eliminate design complexity and accelerate time-to-market in the smart home and building industries,” said Pedro Pachuca, Director of IoT for Semtech’s Wireless and Sensing Products Group, in a statement. “This new reference design is key to our LoRa offerings as more real estate and commercial managers, as well as consumers, look for solutions that solve their daily challenges, such as meeting room occupancy and temperature/humidity monitoring.”
The LoRa-based gateway baseband transceiver achieves 125 kHz LoRa reception. It provides 8 x 8 channels of LoRa packet detectors, 8 x SF5-SF12 LoRa demodulators, 8 x SF5-SF10 LoRa demodulators, a 125/250/500 kHz LoRa demodulator, a (G)FSK demodulator, and a direct interface to Semtech transceivers.
The SX1250 Multi-band Sub-GHz Radio Frequency Front End (SX1250) provides +22dBm output power, lower UHF bands of 169 and 433 or 490 MHz, a 915 MHz North America band and a 868 MHz Europe band.
