User Supplied Equipment
• High power supply − Size is 2x rated power of Power Amplifier at rated voltage
of the final transistor − Suggest using TDK Lambda or MeanWell server brick style
• Load − Suggest using Bird or Dielectric labs that are rated for
frequency and power of the PA • Cooling method − Easiest is large heatsink with 6-inch square flat surface to
mount the PA. − 6 x 12, 3-inch high will suffice for 100 W without fan, 250 W with fan
• Connecting cable between PA and load − Be careful to select a cable suitable for the power of the
amplifier and have minimum loss − Bigger is better
