3. Class D RF amplifier module

As previously mentioned, the RF amplification system of each amplifier block is made up of a large number of identical amplifier modules.

Amplifier modules can be made broadband, so they can be used on long- and medium-wave, at any frequency, without any adjustment.

These modules play an essential role in achieving performance, particularly in terms of emitter efficiency. For this reason, a typical detailed description is given in figure 4 .
