MAX3522B Evaluation Kit

General Description

The MAX3522B evaluation kit (EV kit) simplifies the

testing and evaluation of the MAX3522B DOCSIS 3.1

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.

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.

Quick Start

Required Equipment

● MAX3522B EV Kit Board (included)

● One power supply capable of supplying at least

2000mA at +5V

● One RF signal generator capable of delivering at

least -10dBm of output power at up to 204MHz

frequency (HP8482A or equivalent)

● One RF spectrum analyzer capable of covering the

operating frequency range of the device

● One Windows PC with available USB port

● Two 50Ω SMA cables

● Mini-USB type A-to-type B cable

● (Optional) One network analyzer to measure return loss

● (Optional) One ammeter to measure supply current

Procedure

This section provides a step-by-step guide to testing the

basic functionality of the EV kit.

1) With its output disabled, set the DC power supply to

+5V. If available, set the power supply’s current limit

to 2000mA. Connect the power supply to the +5V

(through an ammeter if desired) and GND terminals

on the EV kit, as shown in Figure 1.

2) With its output disabled, set the RF signal generator

to 85MHz and a power level of -20dBm. Connect

the output of the RF signal generator to the SMA

connector labeled J1 RF IN on the evaluation board,

as shown in Figure 1.

3) Connect the SMA connector labeled J2 RFOUT1 or

J3 RFOUT2 on the evaluation board to a spectrum

analyzer, as shown in Figure 1.

4) Connect the USB cable from FT4232 module’s USB

mini-B port to PC USB port, as shown in Figure 1.
