1. A method of switching a radio frequency signal being capable of representation by a voltage component and a current component the product of which approximates a signal power, said method comprising the steps of:

  • (a) processing the radio frequency signal to provide a processed signal by decreasing said voltage component and increasing said current component, such that the signal power of said processed signal remains substantially identical to said radio frequency signal; and

    ,(b) coupling said processed signal to a radio frequency ground when switching the radio frequency signal to the radio frequency ground, and converting said processed signal to provide an output signal by increasing said voltage component and decreasing said current component, such that said output signal is substantially identical to said radio frequency signal, when switching the radio frequency signal to an output port.
