13.2 Recommendations for building the application
board
• General
– Double-sided board
– Short HF loops by large ground plane on the rear
– SMD components with minimum parasitics.
• Voltage outputs
– Capacitive loads as small as possible
– Be aware of internal output resistance (80 Ω).
• Supply voltages
– Capacitors as near as possible to the pins
– Use electrolytic capacitors with small serial
resistance and inductance.
• Smearing
– Additional peaking circuit at emitter of driver
transistor of cascode stage (time constant
approximately 100 ns).
