MAX2031 Evaluation Kit
General Description
The MAX2031 evaluation kit (EV kit) simplifies the evalua-
tion of the MAX2031 WCDMA, cdma2000^®, GSM, and
WiMAX^(SM) base-station up/downconversion mixer. It is
fully assembled and tested at the factory. Standard 50Ω
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.
