S2-LPQTR

S2-LPQTR is an ultra-low power, high performance, sub-1GHz transceiver intended for RF wireless applications. 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 500Kbps. The S2-LP can be used in systems with channel spacing down to 1KHz enabling the narrow band operations. The S2-LP shows an RF link budget higher than 140dB for long communication ranges and meets the regulatory requirements applicable in territories worldwide, including Europe, Japan, China and the USA. Typical applications include sensors to Cloud, smart metering, home energy management systems, wireless alarm systems, smart home, building automation, industrial monitoring and control, smart lighting systems.
