Lowest Power Integrated UHF RF Transceiver Evaluation Kit

The SX1211SKA is a USB evaluation tool designed to allow simple and easy evaluation of the suitability of the SX1211 for a given application.

The SX1211 is a single chip transceiver IC designed for operation in the European 868 MHz and U.S. 915 MHz licence free ISM bands. The SX1211 is optimized for very low power consumption (3mA in receiver mode). It incorporates a baseband modem with data rates up to 200 kb/s. Data handling features include a sixty-four byte FIFO, packet handling, automatic CRC generation and data whitening. Its highly integrated architecture allows for minimum external component count whilst maintaining design flexibility. All major RF communication parameters are programmable and most of them may be dynamically set.
