1. A switching linear amplifier comprising:

  • a DC-DC converter to increase a low input DC voltage to a first high voltage DC;

    a high voltage high frequency inverter coupled to the DC-DC converter to generate high voltage pulses;

    a multistage voltage multiplier coupled to the high voltage high frequency inverter to generate a second high voltage DC; and

    a controlled charge and discharge circuit coupled to the multistage voltage multiplier to drive a capacitive load;

    wherein the controlled charge and discharge circuit comprises;

    a first series stacked N-channel MOSFETs with balancing resistors for a controlled charge; and

    a second series of stacked N-channel MOSFETs with balancing resistors for a controlled discharge.
