Overview

This document provides technical details for the ADRF5716-EVALZ evaluation board, designed to test the ADRF5716 2-bit digital attenuator. The ADRF5716 is manufactured using a silicon on insulator (SOI) process and offers an attenuation control range of 48 dB (0, 16, 32, and 48 dB states). The 4-layer evaluation board features Rogers 4003 dielectric material, 2.92 mm RF connectors, and a dedicated thru line for calibration. The guide includes a biasing sequence, control voltage truth tables, S-parameter performance plots, a complete circuit schematic, and a detailed bill of materials featuring components from Murata, Yageo, and Components Corporation.
