Composite Video Summer
The bandwidth and differential gain/phase performance
of the FHP3130/3230/3430 amplifiers make them well
suited for video applications. Figure 30 shows a typical
Composite Video Summer. The high output current capa-
bility allows for driving multiple video loads. Figure 31
shows the resulting differential gain/phase of this three-
amplifier configuration driving four video loads, or 37.5W.
Layout Considerations
General layout and supply bypassing play major roles
in high-frequency performance. Fairchild has evaluation
boards to guide high-frequency layout and aid device
testing and characterization. Follow the guidelines 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.
