Analog Devices Inc. EVAL-ADF7024DB2Z

Overview

EVAL-ADF7024DB2Z from Analog Devices is an evaluation board for the ADF7024 ultralow-power sub-GHz FSK/GFSK transceiver IC, supporting 431–435 MHz and 862–928 MHz ISM/SRD bands, data rates up to 300 kbps, and integrated packet handling, smart wake mode, and RF calibration. It enables rapid prototyping of battery-powered wireless sensor networks and IoT endpoints.

For engineers reviewing the EVAL-ADF7024DB2Z datasheet, EVAL-ADF7024DB2Z pinout, EVAL-ADF7024DB2Z application, or EVAL-ADF7024DB2Z equivalent, this board provides validated reference design, SPI-controlled radio profiling, autonomous carrier sense, RSSI monitoring, and calibrated RF front-end matching - all critical for ETSI EN 300-220 and FCC Part 15.247 compliance validation.

Technical Context

The EVAL-ADF7024DB2Z implements the full ADF7024 transceiver IC in a 5 mm × 5 mm, 32-lead LFCSP package with matched 50 Ω RF interface, integrated 26 MHz crystal oscillator, and configurable GPIOs (GP0–GP5, IRQ_GP3). It supports six predefined radio profiles covering 9.6–300 kbps FSK/GFSK modulation with programmable output power (−20 to +13.5 dBm) and automatic frequency/AGC control.

Board-level features include on-board temperature sensor (±4°C accuracy), 8-bit ADC, battery monitor (1.7–2.7 V alarm range), and smart wake controller enabling autonomous Rx sniffing at 11.75 µA average current. All analog regulators (CREGRF1/2, CREGVCO, CREGSYNTH, CREGDIG1/2) and bias networks (RBIAS, CWAKEUP) are populated per ADF7024 layout guidelines.

FAQ

What is the primary function of the EVAL-ADF7024DB2Z evaluation board?

The EVAL-ADF7024DB2Z evaluation board is a fully assembled and tested hardware platform for evaluating the ADF7024 ultralow-power sub-GHz transceiver IC. It provides immediate access to all device interfaces including SPI, GPIOs, RF I/O, and auxiliary blocks (temperature sensor, ADC, battery monitor), enabling rapid validation of radio performance, protocol stack integration, and regulatory testing without custom PCB design. The board ships with firmware-ready configuration for all six radio profiles.

Does the EVAL-ADF7024DB2Z support both 433 MHz and 868/915 MHz bands out of the box?

Yes, the EVAL-ADF7024DB2Z supports operation across 431–435 MHz and 862–928 MHz bands as defined by the ADF7024 IC. Its RF front-end is optimized for 868/915 MHz with SMA-connected matching networks, while 433 MHz operation requires minor external component adjustment per UG-698 hardware reference manual - confirmed in ADF7024 Rev. B datasheet Table 1 (Radio Profile B explicitly covers 431–435 MHz).

Can the EVAL-ADF7024DB2Z be used for FCC or ETSI certification testing?

Yes, the EVAL-ADF7024DB2Z implements the ADF7024 per manufacturer-recommended layout, decoupling, and RF matching guidelines, making it suitable as a baseline for pre-compliance and formal certification testing under FCC Part 15.247 and ETSI EN 300-220. Final certification requires system-level testing with host MCU, antenna, enclosure, and firmware - but the board provides the validated RF section required for repeatable measurements.

What power consumption modes are accessible via the EVAL-ADF7024DB2Z?

The EVAL-ADF7024DB2Z enables full characterization of ADF7024's low-power states: PHY_OFF (1 mA), PHY_ON (1 mA), PHY_RX (12.8 mA), PHY_TX (23.3 mA at 10 dBm), and deep sleep modes - including PHY_SLEEP Mode 1 (0.33 µA with memory retention) and Smart Wake Mode (11.75 µA autonomous reception at 300 kbps). Current measurement test points are provided on the board for each supply rail.

Is SPI communication supported natively on the EVAL-ADF7024DB2Z without additional hardware?

Yes, the EVAL-ADF7024DB2Z exposes the full 4-wire SPI interface (SCLK, MOSI, MISO, CS) on standard 0.1″ headers with proper signal integrity routing and pull-up resistors (e.g., 100 kΩ on CS). It is compatible with common development tools including Analog Devices' SmartRF Studio, IAR Embedded Workbench, and custom microcontroller hosts - no level-shifting or adapter required for 3.3 V logic systems.
