Sub-1 GHz RF transceiver

18 April 2018 Telecoms, Datacoms, Wireless, IoT

The S2-LP from STMicroelectronics is an ultra-low-power RF transceiver, intended for RF wireless applications in the sub-1 GHz band. It is designed to operate in both the license-free ISM and SRD frequency bands at 433, 512, 868 and 920 MHz, but can also be programmed to operate at other frequencies in the 413 - 479 MHz, 452 - 527 MHz, 826 - 958 MHz, and 904 - 1055 MHz bands.

The device supports different modulation schemes: 2(G)FSK, 4(G)FSK, OOK and ASK. The air data rate is programmable from 0,1 to 500 Kbps. The S2-LP can be used in systems with channel spacing down to 1 kHz, enabling narrowband operations.

The S2-LP exhibits an RF link budget higher than 140 dB for long communication ranges, and meets the regulatory requirements applicable in territories worldwide, including Europe, Japan, China and the USA.
