MAX2831 Evaluation Kit

General Description

The MAX2831 evaluation kit (EV kit) simplifies testing 

of the MAX2831 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

Connections and Setup

This section provides step-by-step instructions for getting 

the EV kit up and running in all modes (see 

Figure 1

 for 

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

 connector. Connect the 25-pin connector of 

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

REG

 (pin 1), VCCAUX, and a +3.3V 

power  supply  to  V

BAT

.  Connect  the  power-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 default 

positions as shown in 

Figure 1

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  MAX2831  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 to its default position 2-3  (ANT1).

2)  Set the signal generator to accurately deliver -100dBm 

at 2438MHz, at the SMA port (ANT1/RXRF) of 

MAX2831. Connect the output of signal generator to 

RXRF port of MAX2831.

3)  On the Registers page of the EV kit software, set the 

register values to the recommended setting in the 

MAX2831 data sheet by clicking the "Defaults" and 

“Send All” buttons. 

4)  On the Entry page, confirm that the "Receive Mode" is 

set to “normal,” "Baseband Filter Mode  Control" is set 

to “RX,” and the "RF frequency" is tuned to 2437MHz. 

Maximize the RX LNA and RX VGA Gain.

5)  Connect  the  spectrum  analyzer  to  either  RXBBI  or 

RXBBQ. Set the center frequency to 1MHz with a span
