Abstract
A parametric amplifier is investigated in which three signal frequencies fl, f2 and f3 in addition to the pump frequency fo are used in the external circuits. The energy relationship and the possible power gain in selected cases of up-conversion and straight amplification of a signal are discussed. It is shown that a positive or a negative input impedance can be produced during upconversion and a gain towards infinity can be achieved during upconversion and straight amplification of a signal the frequency of which is greater than the pump frequency.
