Note: Indicate that you are using the MAX2769/MAX2769B/MAX2769C when contacting these component suppliers.

The MAX2769/MAX2769B/MAX2769C EV kit includes two on-board MAX8510 linear regulators for powering up the MAX2769/MAX2769B/MAX2769C device to a regulated supply voltage of +2.85V. When using the linear regulators, connect pins 1-2 of jumpers W16 and W17. The MAX2769/MAX2769B/MAX2769C can also be powered directly through an external power supply through pin 2 of the jumpers (see Figure 1 for details).

An RF spectrum analyzer that covers the MAX2769/ MAX2769B/MAX2769C operating frequency range (e.g., FSEB20, or equivalent) A power supply capable to +6V One ammeter for measuring the supply current (optional) 50 SMA cables A network analyzer (e.g., 8753D or equivalent) to measure small-signal return loss (optional) A dual power supply capable of delivering 5V A user-supplied IBM-compatible PC Oscilliscope or logic analyzer to measure digital outputs (optional)

This section lists the recommended test equipment to verify operation of the It is intended as a guide only and some substitutions are possible. One RF signal generator capable of delivering at least +5dBm of output power at the operating frequency (e.g., E4433B or equivalent)

defaults, also set the SHDN and IDEL pins to 1, under "Entry" page, Hardware Control section. Upon device power-up, the default state should set the MAX2769 device in automatic-gain-control mode (AGCMODE = 00, PGAIEN = 1, and PGAQEN = 0). The default configuration will set the center frequency to 3.9MHz and a bandwidth of 2.5MHz. Using the control software, configure the following: a) In the "Entry" page of the graphical user interface (GUI), set the reference frequency 16.368MHz. b) Set the R divider to 16. c)Enable the I and Q channels by setting the IQ enable 1. d) Set the "output level" 1X = analog outputs through the "Entry" page or configuration register 2. 12)Activate the RF generator and observe the IF signal at an I_OUT_ANA SMA connector J3. 13)Set the "output level" 00 = CMOS logic through the "Entry" page and observe the ADC digital output at J9AJ9D header pins.

a step-by-step guide to operating the device functions. Caution: Do power or RF signal generators are completed.

1) Connect the PC to the INTF3000 interface board using the USB cable. On the INTF3000, remove jumper JU1, and connect a DC supply set +3V to the VPULL connector. Connect the 25-pin connector of the INTF3000 (J4) directly to the 25-pin connector of the EV kit (JDR1). 2) Connect a DC supply set to +3V (through an ammeter if desired) to jumpers W19 and W20 on the EV kit. Do not turn on the supply. When using the on-board linear regulators to power the MAX2769/MAX2769B/ MAX2769C, connect pins 1-2 of jumpers W16 and W17. 3) Connect a DC supply set +5V to jumper W12 on the EV kit. Connect a DC supply set -5V to jumper W11 on the EV kit. Do not turn on the supply. 4) Make sure that jumpers W1W9 and W18 are shorted for proper supply connection. 5) Leave jumpers W14, W15, and W28 open and connect jumper W23 to ground (pins 1-2) if the MAX2769/MAX2769B/MAX2769C is evaluated using a 3-wire bus. 6) Set the signal generator -110dBm. Do not turn on the generator's output. Connect the RF signal generator to the LNA1 input. 7) Connect LNA_OUT SMA connector (J8) to the MIX_IN SMA connector (J12) on the EV kit. 8) Connect the output of the MAX4444 buffer (connector J3) on the EV kit to a spectrum analyzer. 9) Turn on the DC supply. The supply current should read approximately 20mA. 10)Visit HERE to download the latest version of the EV kit software, Max2769A_Setup_2-0-1.exe (for MAX2769EVK), Max2769B_Setup_2-0-1.exe (for or MAX2769C_Setup_1.0.0.exe (for MAX2769CEVK). Run the installation file. 11)Run the control software on an IBM-compatible PC. Load the default state by clicking Settings, then

A good PCB is an essential part an RF circuit design. The EV kit PCB can serve as a guide for laying out a board using the devices. Keep traces carrying RF signals as short as possible to minimize radiation and insertion loss. Use impedance control on all RF signal traces. The exposed paddle must be soldered evenly to the board's ground plane for proper operation. Use abundant throughputs beneath the exposed paddle and between RF traces to minimize undesired RF coupling. To minimize coupling between different sections of the IC, each VCC pin must have a bypass capacitor with low impedance to the closest ground at the frequency of interest. Do not share ground vias among multiple connections to the PCB ground plane. Refer to the Layout Issues section of the MAX2769/MAX2769B/MAX2769C IC data sheet for more information.
