AD8369
Evaluation Board
The evaluation board allows for quick testing of the AD8369
using standard 50 W test equipment. The schematic is shown in
Figure 9. Transformers T1 and T2 are used to transform 50 W
source and load impedances to the desired 200 W reference level.
This allows for broadband operation of the device without the need
to pay close attention to impedance matching (see Table III).

Evaluation Board Software
The evaluation board comes with the AD8369 control software
that allows for serial gain control from most computers. The
evaluation board is connected via a cable to the parallel port of
the computer. By simply adjusting the slider bar in the control
software, the gain code is automatically updated to the AD8369.
On some older PCs, it may be necessary to use 5 kW pull-up
resistors to VPOS on DATA, CLOCK, and LATCH depending
upon the capabilities of the port transceiver.
It is necessary to set SW3 on the evaluation board to “SER” for
the control software to function normally.
A screen shot of the evaluation software interface is shown in
Figure 11.
