1. A radio frequency generator for applying RF power to a load, comprising:

  • a DC power supply;

    at least one switch that generates the RF power at a center frequency; and

    a low-pass terminated network connected between the DC power supply and the switch and having a first cutoff frequency that is less than the center frequency, the low-pass terminated network providing offline impedance control at a frequency less than the center frequency; and

    a high-pass filter interposed between an output of the switch and the load, the high-pass filter having a second cutoff frequency less than the center frequency, the high-pass filter providing inline isolation of the switch from the load at a frequencies less than the center frequency.
