General Description

The MAX2031 evaluation kit (EV kit) simplifies the evalua-

fully assembled and tested at the factory. Standard 50

Ω

SMA connectors are included on the EV kit’s input and

output ports to allow quick and easy evaluation on the

test bench.

This document provides a list of test equipment required

to evaluate the device, a straightforward test procedure

to verify functionality, a description of the EV kit circuit,

the circuit schematic, a bill of materials (BOM) for the kit,

and artwork for each layer of the PC board.
