The S2-LP is a high performance 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 additional frequencies in the 413-479 MHz, 452-527 MHz, 826-958 MH, 904-1055 MHz bands.
The S2-LP 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 the narrow band operations.
The S2-LP shows 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.
