ADF7021BCPZ-RL7

ADF7021 is a high performance narrow-band transceiver IC. It is designed to operate in the narrow-band, license-free ISM bands. It 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 this very suitable for price sensitive and area sensitive applications. It also supports protocols that dynamically switch between 2FSK/3FSK/4FSK to maximize communication range and data throughput. Typical applications are narrow-band standards, ETSI EN 300 220, FCC Part 15, FCC Part 90, FCC Part 95, ARIB STD-T67, low cost, wireless data transfer, remote control/security systems, wireless metering, private mobile radio, wireless medical telemetry service (WMTS), keyless entry, home automation, process and building control, pagers.
