Notes:
1. The thermal resistance is referenced from the junction-
to-case at a case temperature of 85 C. Tjc is a function
of the voltage at pins 6 and 7 and the current applied to
pins 6, 7, and 8 and can be calculated by:
Tjc = Tcase + Rth * Vcc * Icc
2. This corresponds to the typical biasing condition of +5V,
450 mA at an 85 C case temperature. A minimum
MTTF of 1 million hours is achieved for junction
temperatures below 247 C.

A heatsink underneath the area of the PCB for the mounted
device is strictly required for proper thermal operation.
Damage to the device can occur without the use of one.
Ground / thermal vias are critical for the proper performance
of this device. Vias should use a .35mm (#80 / .0135” )
diameter drill and have a final plated thru diameter of .25
mm (.010” ).
Add as much copper as possible to inner and outer layers
near the part to ensure optimal thermal performance.
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.
Do not put solder mask on the backside of the PC board in
the region where the board contacts the heatsink.
RF trace width depends upon the PC board material and
construction.
Use 1 oz. Copper minimum.
All dimensions are in millimeters (inches). Angles are in
degrees.
