GENERAL DESCRIPTION

The EV-ADF5904SD2Z evaluation board allows the user to

evaluate the performance of the ADF5904 24 GHz receiver

downconverter. Figure 1 shows the board, which contains the

ADF5904, five high frequency SMA connectors for the local

oscillator (LO) input, four receiver (Rx) inputs, eight SMA

connectors for the baseband outputs, banana connectors for

power supply, and a connector for serial interface.

The evaluation kit also contains software that is compatible with

Windows® XP and later versions to allow easy programming of

the device.

This evaluation board requires an EVAL-SDP-CS1Z SDP-S

board (not supplied with the kit). The SDP-S board allows

software programming of the ADF5904 device.

Full specifications on the ADF5904 are available in the product

data sheet, which should be consulted in conjunction with this

user guide when working with the evaluation board.

QUICK START GUIDE

Follow these steps to quickly evaluate the ADF5904.

1. Connect the power supply to the EV-ADF5904SD2Z:

a. 5 V to Banana Connector P2

b. GND to Banana Connector P1

2. Install the ADF5904 software.

3. Connect the SDP-S motherboard to the PC and to the

EV-ADF5904SD2Z evaluation board.

4. Follow the hardware driver installation procedure.

5. Run the ADF5904 software.

6. Select the ADF5904 device and the USB board in the

Select Device and Connection tab of the software front

panel window (see Figure 2).

7. Check that the message SDP board connected appears at

the bottom left of the software window (see Figure 2).

8. Connect an ac-coupled RF source to LOIN SMA and

connect an ac-coupled RF source to one of the RXxIN

input SMAs.

9. In the Main Controls tab, click Initialize.

10. Connect the corresponding Rx baseband channel output to

an oscilloscope.

11. Measure the results.

EVALUATION BOARD HARDWARE

The evaluation board requires an SDP-S motherboard to

program the device. The SDP-S board is not included and must

be purchased separately. The EV-ADF5904SD2Z schematics are

shown in Figure 5 to Figure 9. The top layer and assembly layout

are shown in Figure 10.

POWER SUPPLIES

The evaluation board is powered via one external supply, 5 V

connected as described in the Quick Start Guide section.

INPUT SIGNALS

The LO input pin and the Rx input pins on the ADF5904

contain a dc bias voltage; the inputs must be ac-coupled to the

evaluation board.

OUTPUT SIGNALS

The baseband outputs from the ADF5904 contain dc bias

voltages and are available on the J3 to J11 output SMAs.

EVALUATION BOARD SOFTWARE

The control software for the EV-ADF5904SD2Z is included in

the evaluation kit on a CD. To install the software, follow the

on-screen instructions.

To run the software, click the ADF5904 file on the desktop or

from the Start menu.

In the Select Device and Connection tab, select the device and

the connection method, and click Connect.

Confirm that Analog Devices Eval Board connected is

displayed at the bottom left of the window (see Figure 2).

Otherwise, the software has no connection to the evaluation

board.

Note that, when connecting the board, it takes approximately

5 sec to 10 sec for the status label to change.

The Main Controls tab controls the ADF5904 device settings

(see Figure 3).

This tab allows the user to select general options available for

the ADF5904, including power up/down control and register

readback.

On initial power-up of the device, click the Initialize button

to perform the initialization sequence as described in the

ADF5904 data sheet.

EVALUATION AND TEST

To evaluate and test the performance of the ADF5904, take the

following steps:

1. Install the SDP-S software drivers. Connect the evaluation

board to a PC using the supplied USB cable. Follow the

hardware driver installation procedure that appears.

2. Connect the SDP-S connector to the EV-ADF5904SD2Z.

3. Install the ADF5904 software.

4. Connect an ac-coupled RF signal to LOIN SMA.

5. Connect an ac-coupled RF signal to the RX1IN input SMA.

6. Connect a 1 MΩ, ac-coupled oscilloscope to the J3 and J4

output SMAs.

7. Run the ADF5904 software.

8. Select the SDP-S board and the ADF5904 device in the

Select Device and Connection tab of the software window.

9. In the Main Controls tab, click Initialize to power up the

ADF5904 (see Figure 3). See Figure 4 for the suggested

setup.

10. Measure the baseband output signals.
