Typical Application Circuit
Exposed Pad RF and Thermal
Considerations
The exposed pad (EP) of the devices 36-pin thin QFN
package provides a low thermal-resistance path to
the die. It is important that the PCB on which the IC is
mounted be designed to conduct heat from this contact.
In addition, provide the EP with a low-inductance RF
ground path for the device.
The EP MuST be soldered to a ground plane on the
PCB, either directly or through an array of plated via
holes. Soldering the pad to ground is also critical
for efficient heat transfer. Use a solid ground plane
wherever possible.
