Analog Devices Inc. EVAL-ADF7024DB1Z

Overview

EVAL-ADF7024DB1Z 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 with 240-byte Tx/Rx buffer. It enables rapid prototyping of wireless sensor networks and IoT endpoints requiring regulatory compliance (ETSI EN 300 220, FCC Part 15.247).

For engineers reviewing the EVAL-ADF7024DB1Z datasheet, EVAL-ADF7024DB1Z pinout, EVAL-ADF7024DB1Z application, or EVAL-ADF7024DB1Z equivalent, this board provides full access to the ADF7024's SPI interface, smart wake mode (SWM), autonomous carrier sense, integrated ADC/temperature sensor/battery monitor, and RF performance validation across six preconfigured radio profiles.

Technical Context

The EVAL-ADF7024DB1Z implements the ADF7024 transceiver in a complete reference design with matched 50 Ω RF front-end, calibrated low-IF receiver, fractional-N PLL synthesizer, and integrated LDOs. It supports all six ADF7024 radio profiles-including Profile F at 300 kbps-and validates key timing parameters like PHY_ON-to-PHY_RX (300 μs) and SPI interface compliance (t2 ≥ 85 ns setup).

Board-level features include external 26 MHz crystal oscillator with load capacitance tuning, RC wake-up timer (32.768 kHz), GPIO test points (GP0–GP5_ATB1), analog test pins (ATB2–ATB4), and ADCIN_ATB3 input-enabling full characterization of the ADF7024's auxiliary blocks including ±45 mV battery monitor accuracy and −40°C to +85°C temperature sensing.

FAQ

What is the primary function of the EVAL-ADF7024DB1Z evaluation board?

The EVAL-ADF7024DB1Z evaluation board is a fully assembled and tested hardware platform for evaluating the ADF7024 ultralow-power sub-GHz FSK/GFSK transceiver IC. It provides immediate access to all critical interfaces-including SPI, GPIOs, RF I/O, and auxiliary sensors-to validate RF performance, power consumption, packet handling, and smart wake mode operation without custom PCB design. The board ships with firmware enabling quick out-of-box testing of all six radio profiles.

Does the EVAL-ADF7024DB1Z support both 433 MHz and 868/915 MHz frequency bands?

Yes, the EVAL-ADF7024DB1Z supports both 431–435 MHz and 862–928 MHz ISM/SRD bands as defined by the ADF7024 transceiver. Radio Profile B explicitly covers 431–435 MHz, while Profiles A–F operate across 862–928 MHz. The board's RF layout and matching network are optimized for these ranges, and its SMA connector allows direct connection to spectrum analyzers or antennas tuned for either band.

How does the EVAL-ADF7024DB1Z enable low-power system validation?

The EVAL-ADF7024DB1Z enables precise low-power system validation by exposing all ADF7024 power modes-including PHY_SLEEP Mode 1 (0.33 μA), PHY_SLEEP with active 32 kHz RC oscillator (0.75 μA), and Smart Wake Mode (11.75–21.78 μA average)-via current measurement test points and configurable jumpers. It also integrates the ADF7024's battery monitor and temperature sensor, allowing real-time correlation between environmental conditions and power state transitions during autonomous reception cycles.

Can the EVAL-ADF7024DB1Z be used to verify regulatory compliance for ETSI EN 300 220 or FCC Part 15.247?

Yes, the EVAL-ADF7024DB1Z implements the ADF7024's certified radio profiles and on-chip features required for ETSI EN 300 220 and FCC Part 15.247 compliance-including automatic frequency control (AFC), image rejection calibration, spurious emission suppression, and programmable output power (−20 to +13.5 dBm in 0.5 dB steps). While final certification requires conducted/radiated emissions testing on the end-product, this board provides the validated RF foundation and register settings needed for pre-compliance verification.

What software and documentation accompany the EVAL-ADF7024DB1Z?

The EVAL-ADF7024DB1Z ships with the ADF7024 Hardware Reference Manual (UG-698), full register map, SPI command set documentation, and PC-based evaluation software supporting GUI-driven configuration of radio profiles, packet transmission/reception, RSSI monitoring, and auxiliary block control (ADC, temperature, battery). Analog Devices also provides reference firmware source code and application notes covering antenna matching, PCB layout guidelines, and regulatory test procedures specific to the EVAL-ADF7024DB1Z platform.
