STMicroelectronics | SPIRIT1QTR

The SPIRIT1QTR is a very low-power RF transceiver, intended for RF wireless applications in the sub-1 GHz band.

It is designed to operate both in the license-free ISM and SRD frequency bands at 169, 315, 433, 868, and 915 MHz, but can also be programmed to operate at other additional frequencies in the 300-348 MHz, 387-470 MHz, and 779-956 MHz bands.

The air data rate is programmable from 1 to 500 kbps, and the SPIRIT1 can be used in systems with channel spacing of 12.5/25 kHz.
