ABSTRACT:
An RF amplifier arrangement for providing output signals having a controlled frequency distribution and wherein the amplitude and phase of the input signals to an RF amplifier are controlled as a function of the amplitude and phase, respectively, of the output signals from the RF amplifier and also the amplitude of the input signals are adjusted so as to cause the power of the output signal to vary in accordance with a predetermined sequence, whereby such amplitude control of the input signals results in a modified frequency distribution in the energy of the output signals.
