ADF7025:  ISM Band Transceiver IC

Product 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, 862 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.

The ADF7025 transceiver is suitable for operation under FCC 15.247 Digital Modulation Specification characterized by large deviation frequencies. This allows up to 1Watt transmit power without the need to frequency hop, thereby significantly reducing protocol overhead.

Functional Block Diagram for ADF7025

Of Note ...

An Evaluation setup consists of two boards, a small form-factor radio module or daughter board (DB) and a mother board (MB) for interface to the PC. These need to be ordered separately. There are two different variations of mother board, a basic connector board (EVAL-ADF70XXMB) and a controller board with an embedded controller (EVAL-ADF70XXMB2) Please see Evaluation Boards for more information.
