ABSTRACT:
A high frequency amplifier comprises an amplifier stage connected in a grounded base configuration, or a plurality of such amplifier stages connected in tandem, for amplifying high frequency pulses. In order to produce high frequency pulses wherein the output power has a required pulse shape, at the emitter side of each amplifier stage a constant current source is connected which is controlled by a pulse generator which is operable to provide a current having a pulse shape which corresponds to the pulse shape which is the same as the input high frequency pulses.
