RF Evaluation and Development Kits, Boards provide engineers a platform to test out and measure the performance of components, or modules for wireless applications. With extensive measurement capabilities, engineers can assess important radio frequency (RF) performance parameters like modulation accuracy, noise figure, and power gain. The Analog Devices EVAL-ADF7021-NDBZ5 is a development and evaluation platform for low-power, wide-area (LPWA) Internet of Things (IoT) networks. It’s been designed to enable evaluation of the ADF7021, which is a radio transceiver IC, allowing for a robust link budget as well as low-power consumption, while still creating a considerable range with a single node. This board’s functions and features were specifically created to enable engineers to quickly evaluate and develop IoT and LPWA systems.

Application Field

The EVAL-ADF7021-NDBZ5 board has been designed to enable evaluation of the ADF7021 radio transceiver IC in LPWA wireless applications. It has been suited for use in municipalities, enterprise, and agricultural systems that need to support larger geographical areas. The evaluation board also contains external components that must be included in the evaluation of any transceiver IC, such as crystal oscillators, resistors, capacitors, amplifiers, and RF connectors. The ADF7021 supports an operating voltage range from 1.8 V to 3.6 V and operates over a range of frequencies from 1500 MHz to 935 MHz. With an output power of up to +17 dBm and a receiver sensitivity of -112 dBm, the ADF7021 is better suited than many other devices for applications requiring superior link budget performance while still allowing for low cost and low power consumption.

Working Principle

The ADF7021 transceiver IC provides high performance 4-FSK/GFSK modulations for LPWA IoT networks. The device features an on-chip power amplifier, an integrated voltage regulator, programmable wake up timers, and a wide 1.8 V to 3.6 V supply range. This allows the device to maintain optimal performance over a range of operating voltages while still drawing minimal power. With a high receiver sensitivity (down to -112 dBm) and link budget performance of up to +17 dBm, the ADF7021 is an ideal choice for applications requiring a robust link budget while still consuming minimal power.

The EVAL-ADF7021-NDBZ5 evaluation board allows engineers to quickly evaluate the performance of the ADF7021 transceiver IC in their IoT or LPWA systems. The board contains all of the necessary external components and connectors required to properly evaluate the ADF7021. It also features optional headers that allow engineers to configure the communication parameters of the board, as well as specify the channel configuration and bit rate of the device. With the EVAL-ADF7021-NDBZ5, engineers can quickly gain a thorough understanding of the ADF7021 transceiver and its impact on their system’s performance.
