Layout Considerations
General layout and supply bypassing play major roles in high
frequency performance. Fairchild has evaluation boards to use
as a guide for high frequency layout and as aid in device testing
and characterization. Follow the steps below as a basis for high
frequency layout:
• Include 6.8µF and 0.01µF ceramic capacitors
• Place the 6.8µF capacitor within 0.75 inches of the power pin
• Place the 0.01µF capacitor within 0.1 inches of the power pin
• Remove the ground plane under and around the part,
• Minimize all trace lengths to reduce series inductances
Refer to the evaluation board layouts shown below for more
information.

Evaluation Board Information
The following evaluation boards are available to aid in the test-
ing and layout of thes devices:
Evalutaion Board Schematics
Evaluation board schematics and layouts are shown in Figures
32 thru 46. These evaluation boards are built for dual supply
operation. Follow these steps to use the board in a single supply
application:
1. Short -V
2. Use C3 and C4, if the -V
connected to the ground plane.
