Our portfolio of sub 1GHz solutions includes transmitters, transceivers and modules supporting a host of different applications in home and building automation (Smart Home and Smart City) as well as industrial process control (Smart Factory) and automated metering infrastructures (Smart Grid, Wireless M-Bus) or, more broadly, for the Internet of Things (IoT). They support network operated in the license-free ISM and SRD frequency bands at 169, 315, 433, 868, and 915 MHz.
ST transmitter and transceivers includes an AES 128-bit encryption co-processor for secure data transfer and support antenna diversity with an integrated antenna switching control algorithm and several modulation schemes such as 2-FSK, GFSK, OOK, ASK, and MSK.
Our Sub 1GHz modules, operating in IMS and SMD band, are based on our transceivers and are equipped with antenna, xtal and balun. Modules are available with or without the host microcontroller for enhanced flexibility. They provide a ready to use solution, fully RF, ETSI, IC and FCC certified, that helps minimize time to volume.
Our ICs and module are supported by an extensive set of evaluation boards, software, firmware and application notes.
SPIRIT1 ultra-low-power sub-GHz RF transceiver
The SPIRIT1 high-performance wireless transceiver boasts an outstanding receiver sensitivity of 120 dBm combined with an unparalleled competitive advantage of extremely low current consumption. This enables SPIRIT1-equipped applications to operate for up to twice the time over existing solutions without the need to replace the batteries. The transceiver also supports advanced technologies such as frequency hopping, auto-acknowledgment and antenna diversity to secure error-free data transmission even in harsh-environmental or challenging-logistical conditions.
