General Description

The MAX2828/MAX2829 evaluation kits (EV kits) simpli-

fy the testing of the MAX2828/MAX2829. The EV kits

provide 50Ω SMA connectors for all RF and baseband

inputs and outputs. Differential-to-single-ended and sin-

gle-ended-to-differential line drivers are provided to

convert the differential I/Q baseband inputs and out-

puts of the MAX2828/MAX2829 to single-ended ports.

The EV kits simplify evaluation of the receive and trans-

mit performance in the corresponding 802.11x bands.

Features

♦ On-Board Line Drivers and Voltage Reference

♦ 50Ω SMA and BNC Connectors on All RF and

Baseband Ports

♦ PC Control Software Available at www.maxim-ic.com

♦ 3-Wire Serial Interface

Follow the instructions in the Connections and Setup

section to test the devices.

Test Equipment Required

This section lists the recommended test equipment to

continuous current

• DC supply capable of delivering -5.0V and 200mA of

continuous current

• DC supply capable of delivering +3.6V and 300mA of

continuous current

• HP 8663A or equivalent low-noise signal source

capable of generating a 20MHz or 40MHz reference

oscillator signal

• Two HP 8648s or equivalent signal sources capable

of generating 0dBm up to 6GHz

• 802.11x I/Q waveform generator (optional)

• HP 8561E or equivalent RF spectrum analyzer with a

minimum 100kHz to 6GHz frequency range

• TDS3012 or equivalent oscilloscope with 200MHz

bandwidth

• IBM PC or a PC compatible with Windows

95/98/

2000/NT 4.0, or later operating system and an avail-

able parallel port

• Male-to-male 25-pin parallel cable, straight through

Connections and Setup

This section provides step-by-step instructions for get-

ting the EV kits up and running in all modes:

1) Install and run the MAX2828/MAX2829 control software.

2) To control the EV kit through the 3-wire interface,

connect the male-to-male 25-pin parallel cable

between the PC and EV kit.

3) With the power supply turned off, connect a +2.7V

power supply to the header labeled VCC (J13).

Connect the power-supply ground to the header

labeled GND (J12).

4) With the power supply turned off, connect a +5V

power supply to the header labeled +5V (J16), and

a -5V power supply to the header labeled -5V (J14).

Connect the power-supply ground to the header

labeled GND (J15).

5) Connect the low-noise signal source to FREF (J9).

6) Turn on the +5V and -5V power supplies, followed

by the +2.7V power supply. Set the low-noise signal

source to 20MHz and 2dBm. Enable the signal

source. The lock indicator should be green.

Receive Mode

To evaluate the devices in receive mode:

1) Set the RXON jumper (JP22) to the On position and

the TXON jumper (JP21) to the Off position.

2) Connect the RF signal source to either RXRFL

(802.11g, J4) or RXRFH (802.11a, J3). Set the RF

frequency to 2437MHz (802.11g) or 5.25GHz

(802.11a). Set the signal power to -100dBm.

3) Set the register setting to the default values listed in

the MAX2828/MAX2829 data sheet by clicking on

the “Send All” button. Use the software to select

between 802.11g and 802.11a modes. In the pro-

gram, set the frequency to either 2437MHz (802.11g)

or 5.25GHz (802.11a). Set the Rx gain to maximum

using either the slider bar or the control bits.

4) Connect the spectrum analyzer to either RXBBI or

RXBBQ. Set the center frequency to 5MHz with a

10MHz span.

5) Turn on the RF signal source. The output at 5MHz

should be approximately -4dBm (802.11g) or

-5dBm (802.11a).

Transmit Mode

To evaluate the devices in transmit mode:

1) Set the TXON jumper (JP21) to the On position and

the RXON jumper (JP22) to the Off position.

2) Connect a 2MHz I/Q signal to TXBBQ and TXBBI.

Set the input amplitude of each channel to

100mV

RMS

3) Set the register setting to the default values listed in

the MAX2828/MAX2829 data sheet by clicking on

the “Send All” button. Use the software to select

between 802.11g and 802.11a modes. In the pro-

gram, set the frequency to either 2437MHz (802.11g)

or 5.25GHz (802.11a). Set the Tx gain to maximum

using either the slider bar or the control bits.

4) Connect the spectrum analyzer to either TXRFL

(802.11g, J1) or TXRFH (802.11a, J2).

5) Turn on the baseband signal sources. The output

at RF should be approximately -2dBm (802.11g) or

-4dBm (802.11a).
