Notes:
1. The thermal resistance is referenced from the junction-to-case at a case.
temperature of 85
C. Tj is a function of the voltage and the current applied. It can
be calculated by:
Tjc = Tcase + Rth * Vcc * Icc
2. This corresponds to the typical biasing condition of +5V, 400 mA at an 85

Mounting Config. Notes
1. A heatsink underneath the area of the PCB for the mounted device
is recommended for proper thermal operation.
Damage to the
device can occur without the use of one.
2. Ground / thermal vias are critical for the proper performance of this
device. Vias should use a .35mm (#80 / .0135

have a final plated thru diameter of .25 mm (.010
”
)
.
3. Add as much copper as possible to inner and outer layers near the
part to ensure optimal thermal performance.
4. Mounting screws can be added near the part to fasten the board to a
heatsink. Ensure that the ground / thermal via region contacts the
heatsink.
5. Do not put solder mask on the backside of the PC board in the
region where the board contacts the heatsink.
6. RF trace width depends upon the PC board material and
construction.
7. Use 1 oz. Copper minimum.
8. All dimensions are in millimeters
