Product overview
Description
The S2-LPTX is a high performance ultra-low power RF transmitter, 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, 868 and 920 MHz, but can also be programmed to operate at other additional frequencies in the 413-479 MHz, 826-958 MH.
The S2-LPTX 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-LPTX meets the regulatory requirements applicable in territories worldwide, including Europe, Japan, China and the USA.
