General Description
The MAX9993 evaluation kit (EV kit) simplifies the evalua-
tion of the MAX9993 UMTS, DCS, and PCS base-station
downconversion mixer. It is fully assembled and tested
at the factory. Standard 50
Ω
SMA connectors are
included on the EV kit for the input and output to allow
quick and easy evaluation on the test bench.
This document provides a list of 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 PC board.
