ADF7024 - 3

Data Sheet GENERAL DESCRIPTION The ADF7024 is an ultralow power, integrated transceiver for use in the license-free ISM bands at 433 MHz, 868 MHz, and 915 MHz. Its ease of use and high performance make it suitable for a wide variety of wireless applications. The ADF7024 is suitable for operation under the European ETSI EN 300-220 regulation, the North American FCC Part 15 regulation, and other similar regulatory standards. The ADF7024 can operate under a number of predefined radio profiles. For each radio profile, optimized register settings are provided for the ADF7024 radio. This ensures...
