MAX2021 Evaluation Kit
General Description
The MAX2021 evaluation kit (EV kit) simplifies the evalu-
ation of the MAX2021 direct upconversion (downconver-
sion) quadrature modulator (demodulator) designed for
RFID handheld and portal readers, as well as single and
multicarrier 750MHz to 1200MHz GSM/EDGE,
cdma2000®, WCDMA and iDEN® base-station applica-
tions. 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 eval-
uation on the test bench using RF test equipment.
This document provides a list of test equipment required
to evaluate the device, a straight-forward 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 PCB.
cdma2000 is a registered trademark of Telecommunications
Industry Association.
iDEN is a registered trademark of Motorola, Inc.
