ADF7025BCP

GENERAL DESCRIPTION

The ADF7025 is a low power, highly integrated FSK transceiver. It is designed for operation in the license–free ISM bands of 433 MHz, 863 MHz to 870 MHz, and 902 MHz to 928 MHz. The ADF7025 can be used for applications operating under the European ETSI EN300-220 or the North American FCC (Part 15) regulatory standards. The ADF7025 is intended for wideband, high data rate applications with deviation frequencies from 100 kHz to 750 kHz and data rates from 9.6 kbps to 384 kbps. A complete transceiver can be built using a small number of external discrete components, making the ADF7025 very suitable for price-sensitive and area-sensitive applications.
