Maxim Integrated MAX2830 Manual

MAX2830 Evaluation Kit

General Description

The MAX2830 evaluation kit (EV kit) simplifies testing
of the MAX2830 receive and transmit performance in
802.11g/b applications operating in the 2.4GHz to 2.5GHz
ISM band. The EV kit provides 50Ω SMA connectors for
all RF and baseband inputs and outputs. Differential-to-
single-ended and single-ended-to-differential line drivers
are provided to convert the differential I/Q baseband
inputs and outputs to single ended.
Features
● On-Board Line Driver and Voltage Reference
● 50Ω SMA Connectors on All RF and Baseband Ports
● PC Control Software Available at

Connections and Setup
This section provides step-by-step instructions for getting
the EV kit up and running in all modes (see
EV kit connections):
1) Connect the PC to the INTF3000 interface board using
the USB-A male to USB-B male cable. On INTF3000,
remove jumper JU1 and connect a DC supply set to 3.3V
to the V
PULL
the INTF3000 (J4) directly to the 25-pin connector on the
EV kit (J18).
2) With the power supply turned off, connect a +2.85V
power supply to V
+3.3V power supply to V
supply ground to the header labeled GND1 or GND2.
3) With the power supply turned off, connect a +5V power
supply to the +5V test point and a -5V power supply to
the -5V test point. Connect the power-supply ground
to the header labeled GND1 or GND2. Connect all the
power-supply grounds together.
4) Make sure the jumpers are installed in their defualt
positions as shown in
5) Turn on the +3.3V power supply, followed by the
+2.85V power supply, +5V power supply, and -5V
power supply.
6) Install and run the MAX2830 control software,
available for download HERE.
Receive Mode
1) Set the RXTX jumper across pins 2-3 (RX) to enable
the receiver and disable the transmitter. Set the
ANTSEL jumper across pins 2-3 (ANT1) to connect
the receiver to the ANT1 port, or pins 1-2 (ANT2) to
connect the receiver to the ANT2 port.
2) Set the signal generator to accurately deliver
-100dBm at 2438MHz, at the SMA port (ANT1 or
ANT2) of MAX2830. Connect the output of signal
generator to ANT1 or ANT2 port of MAX2830.
3) On the Registers page of the EV kit software, set
