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,

especially near the input and output pins to reduce

parasitic capacitance

• Minimize all trace lengths to reduce series inductances

Refer to the evaluation board layouts shown in Figure 6 for

more information.
