The low power baseband transceiver is optimized for data rates up to 40kbp/s and incorporates direct sequence spread spectrum technology to assure reliable data transfer in hostile RF environments. The high level of integration, shown below, includes a thin Media Access Controller, resulting in a minimum of external components and lower application costs.
