For another method to evaluate and test the performance of the

ADF5901, ADF5904, and ADF4159, use the following procedure:

1. Install the EV-RADAR-MMIC evaluation software.

2. Connect the EV-ADAR-D2S evaluation board to the

EV-RADAR-MMIC2 evaluation board.

3. Connect the SDP board to the EV-RADAR-MMIC2.

4. Connect the dc blocked TX_OUT2 (J9) connector to a

delay cable or antenna.

5. Connect a delay cable or antenna to RX4_RFIN (J6)

connector.

6. Run the EV-RADAR-MMIC software.

7. Select the SDP board and the EV-RADAR-MMIC2

(ADF5901, ADF5904, and ADF4159) device in the Select

Device and Connection tab of the software window.

8. The software is set with default conditions for the

following setup:

a. Lock the ADF4159 to 12.0125 GHz (24.025 GHz on

ADF5901).

b. Calibrate the ADF5901 to 24.125 GHz.

c. Generate a 5 ms, 200 MHz triangular ramp (24.025 GHz

to 24.225 GHz).

9. In the ADF5904 Controls tab, click Initialize to power up

the ADF5904.

10. In the ADF4159 Controls tab under the Main Controls

section, click Write All Registers to power up the ADF4159.

11. In the ADF5901 Controls tab, click Initialize ADF5901 to

power up and calibrate the ADF5901. See Figure 8 and

Figure 9 for the typical setups.

12. In the ADF4159 Ramps and Shift Keying tab, enable the

ramp and click Write R0 to enable the ramping of the

ADF5901 Tx outputs.

13. Measure the baseband output signal on the O5 connector on

the EV-ADAR-D2S board.
