**NOTES**

2. DC traces should be 8 mils wide with 10 mils of clearance.

1. RF traces should be 18 mils wide with 20 mils of clearance.

3. Trace widths and clearances apply to application

circuit on 10 mil FR4.

4. Pins 1 and 3 should be tied directly to PCB ground pattern

under the power amplifier, and should form a coplanar

waveguide for the RF In. Ground should also provide a

coplanar waveguide for the RF Out.
