PCB Layout Considerations
The RF3320 Evaluation board can be used as a guide for the layout in your application. Care should be taken in laying
out the RF3320 in other applications. The RF3320 will have similar results if the following guidelines are taken into con-
sideration:
Make sure underside of package is soldered to a good ground on the PCB.
Keep input and output traces as short as possible.
Ensure a good ground plane by using multiple vias to the ground plane.
Use a low noise power supply along with decoupling capacitors.

Notes:
1. 4-layer board.
2. Underside of package must solder to ground.
3. Place C5 and C6 as close to pin as possible.
4. C1 is tantalum, size code Y.
5. All other components are 0603 size.
6. Replace R5 with 0
resistor if 75
connector is used.
