Abstract :
This paper discusses the use of parametric circuits to achieve high power, high efficiency power amplification over wide bandwidths. A new architecture is proposed that uses an upconverting parametric amplifier as a polar modulator. In addition, applications of multiferroic materials to achieve wideband parametric amplification are discussed.
