Product Summary

The ADF7021BC is a low power, highly integrated 2FSK/3FSK/4FSK transceiver. ADF7021BC is designed to operate in the narrow-band, license-free ISM bands and licensed bands in the 80 MHz to 650 MHz and 862 MHz to 940 MHz frequency ranges. It has both Gaussian and raised cosine data filtering options to improve spectral efficiency for narrow-band applications. ADF7021BC is suitable for circuit applications targeted at European ETSI-EN 300-220, the Japanese ARIB STD-T67, the Chinese Short Range Device regulations, and the North American FCC Part 15, Part 90, and Part 95 regulatory standards. A complete transceiver can be built using a small number of external discrete components, making the ADF7021BC very suitable for price-sensitive and area-sensitive applications.
