Abstract
A frequency shifter configured to shift the frequency of a signal, the frequency shifter comprising: a resonant structure configured to mechanically resonate at a first frequency; and a plurality of capacitors, each capacitor having a variable plate separation distance, wherein the resonant structure is configured to cause the plate separation distance of each capacitor to oscillate so as to cause the frequency of the signal to shift by the first frequency.
