MAX9993 Evaluation Kit
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鈩?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.
