RF Power Amplifier

Tube 1P24B as usual is used for RF Power Amplifier. The tube may produce RF- power up to 2.5- Wtt. Figure 5 shows a schematic of an RF Power Amplifier for frequencies up to 100- MHz. Figure 6 shows chart of the main characteristics Vs optimal (Roe) load for the RF Power Amplifier shown on the Figure 5.

Figure 7 shows schematic of an RF Power Amplifier for frequencies higher the 100- MHz. It is usual Push- Pull amplifier. Tubes used at the amplifier should be a matched pair. As usual tubes from one produced batch are the matched pair to each other.
