Abstract:

Parametric effects 1. have been largely used in 1960s up and down frequency conversion, amplification at microwave frequencies 2. are based on time varying properties of a capacitor or inductor Manley-Rowe Equations 3. allow to transfer power from the pump frequency omegasub p to the input signal frequency omegasub s or to the up-conversion frequency omegasub u ...GAIN 4. The source of power for a usual transducer amplifier is a dc supply, for a parametric amplifier the source of power is the pump electrical signal omegasub p, which is a higher frequency than the input signal omegasub s.
