The SX1211 is optimised for asynchronous sensor network designs in the unlicensed industrial, scientific and medical (ISM) frequency bands (868-870 MHz and 902-928 MHz) where low RX power consumption is critical to battery.

The SX1211’s RX current consumption (consumes <3mA) is up to five times lower than competitive solutions, resulting in up to five years in battery life for sensor applications. In addition to a low RX current, the device also features a 64-byte FIFO buffer that enables more power efficient batch data transfers between the transceiver and microcontroller. Transmit power consumption at + 10 dBm is only 25 mA.

All major RF communication parameters are programmable and can be configured dynamically, with RF output power programmable up to +12.5 dBm in eight steps.
