Transceiver saves power for telemetry
The SX1211 UHF transceiver is optimised for designs in the unlicensed industrial, scientific and medical frequency bands from 868to 870 and 902 to 928MHz.
Claiming the industry's lowest receiver (Rx) current consumption (at less than 3mA), which significantly increases battery life in wireless applications, the new SX1211 UHF transceiver from Solid State Supplies is optimised for designs in the unlicensed industrial, scientific and medical (ISM) frequency bands (868-870 and 902-928MHz) Key applications include security and alarm systems, submetering, industrial monitoring and control, building automation and Konnex systems

The MUR range of ultrafast rectifiers from Solid State Supplies have been specifically designed to provide optimised performance of forward voltage drop with a reverse recovery time of 25ns.
Ferroelectric RAM handles repeated rewrites
The FM24C04 4Kbit FRAM serial memory from Solid State Supplies is ideal for nonvolatile memory applications which require frequent or rapid writing.
The SX1211 also features a 64byte FIFO buffer that enables more power efficient batch data transfers between the transceiver and microcontroller.
Transmit power consumption at +10dBm is only 25mA.
Supporting both frequency-shift keying (FSK) modulation and on/off keying (OOK) modulation, the SX1211 can be used for both new and legacy sensor network designs.
It also supports FSK datarates from 1.56 to 100Kbit/s and OOK datarates up to 32Kbit/s.
Receiver sensitivity for FSK modulation is -104dBm at 25Kbit/s and for OOK is -110dBm at 2Kbit/s.
All major RF communication parameters are programmable and can be configured dynamically, with RF output power programmable up to +12.5dBm in eight steps.
Operating over a supply voltage range of 2.1 to 3.6V, the SX1211 meets regulatory standards for both Europe (ETSI EN300-220-1) and North America (FCC parts 15.247 and 15.249), for both digital modulation (DTS) and frequency hopping systems.
