MAX2023 Evaluation Kit
General Description
The MAX2023 evaluation kit (EV kit) simplifies the evalu-
ation of the MAX2023 direct upconversion (downconver-
sion) quadrature modulator (demodulator) designed for
single and multicarrier 1500MHz to 2300MHz
GSM/EDGE, cdma2000^®, and WCDMA and base-sta-
tion applications. 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 using RF test equip-
ment. The EV kit is lead free and RoHS compliant.
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.
