EVALUATION BOARD
The schematic of the AD8346 evaluation board is shown in
Figure 25. This is a 4-layer FR4 board, the two center layers
being used as ground planes and the top and bottom layers
being used for signal and power respectively. The layout and
silkscreen of the top (signal) layer is shown in Figure 26. The
circuit closely follows the basic connections circuit shown in
Figure 21. For normal operation the board’s only jumper should
be in place (connecting ENBL to the supply). If the jumper is

removed, ENBL will be pulled to ground by a 10 k
resistor,
putting the device into its power-down mode.
All connectors are SMA-type. The I and Q inputs are dc coupled
to allow direct connection to a dual DAC with differential out-
puts. The local oscillator input is driven through a balun
(M/A-COM Part Number. ETC1-1-13). To implement a single-
ended drive, remove the balun and replace it with two surface
mount 0
resistors (i.e., from Pin 4 to 3 and Pin 1 to 5 of the
balun).
