The MAX2022 evaluation kit (EV kit) simplifies the evalu-
ation of the MAX2022 direct upconversion (downconver-
sion) quadrature modulator (demodulator) designed for
UMTS/WCDMA, cdma2000
base-station applications. It is fully assembled and test-
ed 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 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.
