Mother Board with ADF7023 io-homecontrol® Compliant RF Transceiver working in channels at 868.25 MHz, 868.95 MHz and 869.85 MHz

The ADF7023 is a very low power, high performance, highly integrated FSK/GFSK transceiver designed for operation at the three io-homecontrol® channels at 868.25 MHz, 868.95 MHz and 869.85 MHz in the license-free ISM band. The ADF7023 is fully compliant to ETSI-300-220, and is based on the popular ADF7020 transceiver with enhanced digital baseband features specifically designed for the io-homecontrol® standard.
