EVALUATION AND TEST PROCEDURES
To evaluate and test the performance of the ADF5901 ,
ADF5904 , and ADF4159 , use the following procedure:
1. Install the EV-RADAR-MMIC2 evaluation software.
2. Connect the EV-ADAR-D2S board to the EV-RADAR-
MMIC2 board.
3. Connect the SDP board to the EV-RADAR-MMIC2 .
4. Connect the dc blocked TXOUT2 connector (J9) to the
spectrum analyzer.
5. Connect 24.026 GHz, −50 dBm signal dc blocked from the
signal source to RX4 connector (J6).
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 settings for the
following setup:
a. Lock the ADF4159 to 12.0125 GHz (24.025 GHz on the
ADF5901 ).
b. Calibrate the ADF5901 to 24.125 GHz.
9. In the ADF5904 Main Controls tab, click Initialize to
power up the ADF5904 .
10. In the ADF4159 Main Controls tab, 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 7 for a
typical setup.
12. Measure a 24.025 GHz signal on TXOUT2 (J9) on the
spectrum analyzer
13. Measure a 1 MHz baseband output signal on the
O5 connector on the EV-ADAR-D2S board.
