Analog Devices Inc. EV-ADF70301-433AZ

Overview

EV-ADF70301-433AZ from Analog Devices is a 433 MHz sub-GHz radio transceiver evaluation kit built around the ADF7030-1 IC, supporting IEEE 802.15.4g and Wireless M-Bus protocols. It delivers −108.6 dBm sensitivity at 50 kbps, dual programmable PAs (−20 to +17 dBm), and on-chip ARM Cortex-M0 for packet handling and calibration - enabling long-range, low-power smart metering and industrial sensor node development.

For engineers reviewing the EV-ADF70301-433AZ datasheet, EV-ADF70301-433AZ pinout, EV-ADF70301-433AZ application, or EV-ADF70301-433AZ equivalent, this board provides validated RF matching, TCXO-stabilized 433 MHz operation, SPI-configurable packet modes (generic/IEEE802.15.4g), and full support for ETSI EN 300 220-1 and FCC Part 15 compliance testing.

Technical Context

The EV-ADF70301-433AZ implements the ADF7030-1 transceiver in a 433 MHz band-specific configuration with separate TX/RX impedance matching networks and a 26 MHz TCXO reference. It supports 2GFSK modulation at 50 kbps with 25 kHz frequency deviation and 200 kHz channel spacing, using a 135.42 kHz IF and 101.57 kHz receiver bandwidth.

This evaluation platform enables full characterization of key ADF7030-1 features: dual PA control (PA1/PA2), clear channel assessment (CCA), forward error correction (FEC), data whitening, and dual-sync word detection - all accessible via standard 4-wire SPI and configurable GPIOs.

FAQ

What is the primary function of the EV-ADF70301-433AZ?

The EV-ADF70301-433AZ is an evaluation kit for the ADF7030-1 sub-GHz radio transceiver, configured for 433 MHz operation. It provides a fully assembled, tested hardware platform with calibrated RF matching, TCXO reference, and firmware-ready SPI interface - enabling immediate validation of packet-based communication, sensitivity, transmit power, and regulatory compliance for systems targeting ETSI EN 300 220-1 or FCC Part 15.

Does the EV-ADF70301-433AZ support IEEE 802.15.4g mode?

Yes, the EV-ADF70301-433AZ supports IEEE 802.15.4g (MR-FSK PHY) out of the box via the onboard ADF7030-1 IC. The evaluation kit's firmware and reference design implement mandatory frame formatting, FEC, interleaving, and dual-sync word detection required by the standard - verified using the 433 MHz/50 kbps test configuration documented in the ADF7030-1 datasheet Rev. A, Table 9.

What oscillator type is used on the EV-ADF70301-433AZ?

The EV-ADF70301-433AZ uses a 26 MHz thermally compensated crystal oscillator (TCXO) as the primary reference, delivering ±0.5 ppm stability over temperature. This ensures the ADF7030-1 achieves ≤±25 ppm RF frequency accuracy at 433 MHz - critical for passing ETSI EN 300 220-1 channel mask and blocking requirements.

Can the EV-ADF70301-433AZ be used for FCC certification testing?

Yes, the EV-ADF70301-433AZ is explicitly validated for FCC Part 15 compliance testing. Its 433 MHz RF front-end, dual PA architecture, and pre-characterized spurious emissions (<−70 dBc harmonics, <−74 dBm non-harmonic) meet conducted emission limits. The board's documented performance in Table 9 (e.g., −108.6 dBm sensitivity, 87 dB blocking at ±20 MHz) aligns with FCC measurement methodologies.

Is external antenna matching required when using the EV-ADF70301-433AZ?

No, the EV-ADF70301-433AZ includes a fully optimized, discrete-component 433 MHz antenna matching network with separate TX and RX paths. The board is shipped with a calibrated 50 Ω SMA connector and requires no additional impedance tuning - enabling direct connection to standard 433 MHz antennas or RF test equipment for accurate link budget analysis.
