EVAL-ADL8141: User Guide for the ADL8141 14 GHz to 24 GHz Low Noise Amplifier
User guide for the ADL8141-EVALZ evaluation board, detailing the 14 GHz to 24 GHz GaAs pHEMT MMIC low noise amplifier with schematics and BOM.
Overview
The EVAL-ADL8141 (UG-2129) provides technical documentation for the ADL8141-EVALZ evaluation board. This board is designed to evaluate the ADL8141, a GaAs, pHEMT, MMIC low noise amplifier (LNA) that operates from 14 GHz to 24 GHz. The document outlines the 4-layer PCB construction using Rogers 4003C and Isola 370HR materials, featuring 50 Ω characteristic impedance RF traces and 2.4 mm end-launch connectors. It includes operating procedures, recommended bias sequencing, a full circuit schematic, assembly drawings, and a bill of materials. The LNA typically requires a 2 V supply and features a through calibration path to account for board trace losses.
