Description

The ZMD44101 is a fully integrated system-on-chip

CMOS transceiver, providing license free multi-

channel operation in the 868.3MHz (EU) and

902MHz to 928MHz (US) ISM bands. 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.
