Analog Devices Inc. EV-ADF70301-460BZ

Overview

EV-ADF70301-460BZ from Analog Devices is a 433–470 MHz sub-GHz radio evaluation board built around the ADF7030-1 transceiver IC. It supports IEEE 802.15.4g and Wireless M-Bus (EN 13757-4), delivers −108.6 dBm sensitivity at 50 kbps, features dual PAs (−20 to +17 dBm), and enables precise RF characterization on the 433 MHz band using a 26 MHz TCXO reference.

For engineers reviewing the EV-ADF70301-460BZ datasheet, EV-ADF70301-460BZ pinout, EV-ADF70301-460BZ application, or EV-ADF70301-460BZ equivalent, this board provides calibrated 433 MHz transmit/receive match, on-board ARM Cortex-M0 firmware control, SPI-configurable packet modes, and ETSI/FCC-compliant RF performance validation for smart metering and industrial WSN designs.

Technical Context

The EV-ADF70301-460BZ implements a dedicated 433 MHz RF front-end with separate TX/RX matching networks optimized for the ADF7030-1's dual PA architecture. It integrates a 26 MHz TCXO for frequency stability and supports both narrowband (2.6 kHz) and wideband (135.42 kHz) receiver channel bandwidths per configuration.

Measurements performed on this board validate key ADF7030-1 specifications including −108.6 dBm sensitivity at 50 kbps, 56 dB adjacent-channel rejection, and −60 dBc adjacent-channel power - all under IEEE 802.15.4g packet mode with 2GFSK modulation and 25 kHz frequency deviation.

FAQ

What is the primary RF band validated on the EV-ADF70301-460BZ evaluation board?

The EV-ADF70301-460BZ evaluation board is specifically configured and characterized for the 433 MHz band, as confirmed by its use in the ADF7030-1 datasheet's Table 8 and Table 9 measurements. All published RF performance data-including −108.6 dBm sensitivity and 56 dB adjacent-channel rejection-were obtained using the EV-ADF70301-460BZ at 433 MHz with 50 kbps 2GFSK modulation. The board's matching network and TCXO are optimized for this band.

Does the EV-ADF70301-460BZ support IEEE 802.15.4g packet mode?

Yes, the EV-ADF70301-460BZ fully supports IEEE 802.15.4g packet mode via the onboard ADF7030-1 transceiver. Its firmware and hardware configuration enable compliant MR-FSK PHY operation, including FEC, interleaving, dual-sync word detection, and frame formatting per the standard. The 433 MHz/50 kbps test setup in the ADF7030-1 datasheet explicitly uses IEEE 802.15.4g packet mode for sensitivity and selectivity validation.

What oscillator type is used on the EV-ADF70301-460BZ board?

The EV-ADF70301-460BZ uses a 26 MHz thermally compensated crystal oscillator (TCXO) as its reference clock source, as stated in the ADF7030-1 datasheet section "433 MHz" and confirmed in Table 8. This TCXO provides the frequency stability required for ETSI EN 300 220-1 and FCC Part 15 compliance, especially critical for narrow-channel applications in smart metering deployments.

Can the EV-ADF70301-460BZ be used to evaluate ADF7030-1 performance at 460 MHz?

No - the EV-ADF70301-460BZ is named for the ADF7030-1's 433–470 MHz operating range but is physically tuned and validated exclusively for 433 MHz, as documented in the ADF7030-1 datasheet's "433 MHz" section. While the ADF7030-1 IC itself supports 460 MHz, the EV-ADF70301-460BZ board's matching network, layout, and measurement data apply only to 433 MHz; no 460 MHz characterization is provided for this specific board.

What is the purpose of the separate TX/RX match design on the EV-ADF70301-460BZ?

The separate transmit and receive matching networks on the EV-ADF70301-460BZ optimize RF performance for each operational state: the TX path maximizes power transfer and spectral purity at +17 dBm output, while the RX path maximizes sensitivity and blocking immunity at −108.6 dBm. This architecture eliminates compromise between transmit efficiency and receive linearity, directly enabling the ADF7030-1's specified 97 dB blocking performance and ultra-low noise figure on the 433 MHz band.
