STMicroelectronics S2-LPQTR, RF Transceiver IC 430MHz to 470MHz Dual Band 24-Pin QFN


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, 868 and 920 MHz, but can also be programmed to operate at other additional frequencies in the 430-470 MHz, 860-940 MHz bands. The S2-LP supports different modulation schemes: 2(G)FSK, 4(G)FSK, OOK and ASK.
