1. A method comprising:coupling one radio frequency device to a device requiring power;
modulating an amplitude of a drive signal for said device requiring power via phase modulation, with a digital control module such that phase modulated sidebands outside the bandwidth of the device requiring power are reflected and only a carrier remains;
controlling said modulated amplitude via said phase modulation according to a modulation depth control signal and a phase modulation signal;
providing said drive signal to said radio frequency device; and
powering said device requiring power with said radio frequency device and removing power associated with said modulated sidebands outside the bandwidth of the device requiring power thereby providing a modulation scheme comprising vector control of a radio frequency vector required for said device requiring power.
