Abstract
The Manley and Rowe equations do no more than give us information on the general operating conditions of a parametric amplifier using a non-linear non-dissipative reactance. The reactances used in practice are semiconductor diodes (varactors) in which losses inevitably occur. The following discussion is intended to enable us to calculate the following quantities, taking into account the losses just mentioned:
-
the gains of the different types of amplifiers;
-
their optimum terminal impedances;
-
their effective noise temperature.
