Analog Devices EVAL-ADRF5702 Evaluation Board User Guide
User guide for the ADRF5702-EVALZ board, evaluating the ADRF5702 8-bit digital attenuator (50MHz to 20GHz) with 0.125dB LSB and a 31.875dB range.
Overview
This document provides comprehensive instructions for the ADRF5702-EVALZ evaluation board, designed to test the ADRF5702 8-bit silicon digital attenuator. The ADRF5702 operates from 50MHz to 20GHz with a 31.875dB attenuation range. The guide includes detailed hardware specifications such as a 4-layer PCB stack-up using Rogers 4003 dielectric for 50Ω controlled impedance, power supply requirements (3.3V/5V), and RF connection details via 2.92mm connectors. It features a complete schematic, assembly diagrams, and a bill of materials listing components from Murata, Passive Plus, Yageo, and Hirose Electronic.
Use Cases
- RF signal chain attenuation control
- Broadband wireless infrastructure
- Microwave point-to-point radios
- Military and space communication systems
- Test and measurement equipment calibration
