Quick Start
The MAX2391/MAX2392/MAX2393 EV kits are fully
assembled and factory tested. Follow the instructions in
the Connections and Setup section for proper device
evaluation.
Test Equipment Required
This section lists the recommeded test equipment to
verify the operation of the MAX2391/MAX2392/
MAX2393 EV kits. It is intended as a guide only, and
some substitutions are possible.
• DC supply capable of delivering 200mA continuous
current at +5.0V
• DC supply capable of delivering 200mA continuous
current at -5.0V
• DC supply capable of delivering 50mA continuous
current at +2.8V
• HP 34401 or equivalent DMM, to measure IC supply
current
• HP8648C or equivalent signal source capable of
generating -30dBm up to 2.2GHz
• HP8561E or equivalent RF spectrum analyzer (base-
band spectrum only)
• TDS3012 or equivalent digitizing oscilloscope
• Windows® 95/98/2000 PC with an available parallel
port
Connections and Setup
This section provides a step-by-step guide to testing
the basic functionality of the EV kits.
This procedure is specific to the MAX2391 in the UMTS
band (reverse channel: 2110MHz to 2170MHz). Adapt
the procedure for the MAX2392 or MAX2393 by chang-
ing the RF frequency of the test tone to suit the band of
interest. The test tone at a 180kHz offset offset works
well for all three parts.
1) Install the MAX2391/MAX2392/MAX2393 control
software on PC. This software uses a 3rd-party DLL
to allow communication through the parallel port:
“DriverLINX” by Scientific Software Tools (www.sst-
net.com). The Maxim intaller will install this DLL for
you automatically.
2) Connect the interface board and cable from the PC
parallel port to the EV kit header. Pin 1 on the rib-
bon cable is indicated with a stripe, and pin 1 on
the header is nearest to the corner of the board.
The interface board is just populated with logic
buffers to protect the parallel port against acciden-
tal shorts, but be careful with these connections.
