Mounting Instructions
1. NOTE: For broadband RF unconditional stability do not
put GND vias under the exposed backside GND paddle.
2. Solder the copper pad on the backside of the
device package to the ground plane.
3. Use a large ground pad area with many plated
through-holes as shown.
4. We recommend 1 or 2 ounce copper. Measurement
for this data sheet were made on a 31 mil thick FR-4
board with 1 ounce copper on both sides.
