Long-range RF transceivers
29 January 2014, Telecoms, Datacoms, Wireless

Semtech has introduced the SX127x devices, which integrate the company’s new LoRa (long range) RF transceiver technology. The SX1276 covers all the major sub-GHz frequency bands while the SX1277 is a cost-optimised version targeted at applications that utilise data rates from 5 Kbps to 40 Kbps such as security systems. The SX1278 is optimised for the rapidly growing smart meter market in China using the 470 – 510 MHz band. All devices deliver over 100 dB of blocking immunity to out-of-band interfering signals, and offer a 25 dB improvement over FSK devices for rejecting in-band interfering signals. This makes the devices especially effective in ISM-band applications such as security and metering because it provides immunity from sub-GHz frequency 4G/LTE signals.
