Quick Start
The MAX2585 EV kit is fully assembled and factory tested.
Follow the instructions in the Connections and Setup
section.
Required Test Equipment
This section lists the recommended test equipment to
verify the operation of the MAX2585. It is intended as a
guide only, and substitutions may be possible:
DC supply capable of delivering +5.0V and 250mA
of continuous current
DC supply capable of delivering -5.0V and 250mA of
continuous current
DC supply capable of delivering +2.5V at low current
(< 1mA) for the gain control voltage (optional)
Signal source capable of operating up to 2.5GHz
RF spectrum analyzer with a minimum 1kHz-to-3GHz
frequency range
IBM PC or compatible with Windows® 95/98/2000/
NT 4.0/XP, or later operating system and an available
parallel port
INTF2300 interface board (supplied with the EV kit)
Connections and Setup
This section provides step-by-step instructions for
getting the EV kit up and running in cellular band
CDMA mode:
1) Verify shunts JU1, JU2, JU3, JU9, JU10, JU16,
JU19, JU23, JU24, JU26, JU28, JU30, JU36, and
JU38 are in place.
2) Verify shunts JU9, JU10, and JU30 are in the ON
(VCC) position.
3) The gain control pin voltage of the MAX2585 can
be controlled by an on-board variable resistor or by
an additional DC power supply. To use the variable
resistor to adjust the gain control voltage, install a
shunt across the two pins of JU24 closest to the
edge of the board. Remove JU24 and connect a
DC power supply to the VGC connector (TP8) on
the board to use an external supply to adjust the
gain control voltage.
4) Connect the INTF2300 interface cable to the EV kit’s
20-pin connector (J17). Note: Pin 1 of the interface
cable corresponds to the red wire. Pin 1 of the con-
nector is indicated on the printed circuit board (PCB)
by a flattened corner in the J17 silkscreen outline.
5) With their outputs turned off, connect a +5.0V
power supply to the header labeled +5V (JU11),
and a -5.0V power supply to the header labeled -5V
(JU20). Connect the power-supply ground to the
header labeled GND (JU12 or JU21).
6) Install and run the MAX2585 control software (avail-
able from the factory).
7) With the MAX2585 control software active in the entry
view screen, select the appropriate device type.
8) In the register-view screen of the control software,
set the registers to typical cellular band CDMA
settings as shown in Table 1.
9) Turn on the +5.0V and -5.0V power supplies. Then
turn on the gain control power supply (optional).
10) Select the resend registers button at the top of the
screen to send all registers to the MAX2585.
11) With its output turned off, connect a continuous
wave RF signal source to CLNA_IN (J3). Set the RF
frequency to 881.1MHz with a -104dBm power level.
12) In either the entry view or register view screen of
the control software, toggle the DC cal pin box from
1 to 0, and then back to 1.
13) Enable the output of the RF signal source.
