Overview

This document provides technical details for the ADRF5740-EVALZ-185 and ADRF5740-EVALZ-292 evaluation boards, designed to test the ADRF5740 10 MHz to 60 GHz, 4-bit silicon digital attenuator. The ADRF5740-EVALZ-185 features 1.85 mm connectors for performance up to 67 GHz, while the ADRF5740-EVALZ-292 uses 2.92 mm connectors for operation up to 40 GHz. The guide includes setup instructions, power supply configurations, a digital control truth table, and a through calibration line description for de-embedding board loss. Also provided are a full schematic, assembly diagrams, and a complete bill of materials including components from Murata, AVX, and Hirose.
