MAX3521 Evaluation Kit
General Description
Features
● Easy Evaluation of the MAX3521
The MAX3521 evaluation kit (EV kit) simplifies the testing
and evaluation of the MAX3521 DOCSIS 3.0 upstream
amplifier. The EV kit is fully assembled and tested at the
factory. Standard 50Ω SMA connectors are included on
the EV kit for the inputs and outputs to allow quick and
easy evaluation on the test bench.
● 50Ω SMA Connectors
● All Critical Peripheral Components Included
● Proven PCB Layout
● Fully Assembled and Tested
This document provides a list of equipment required to
evaluate the device, a straightforward test procedure to
verify functionality, a description of the EV kit circuit, the
circuit schematic, a list of components for the EV kit, and
artwork for each layer of the PCB.
● PC Control Software
