Amplitude and Phase Modulation In Resistive Diode Mixers

This paper presents some new aspects of mixer operation and shows that the behavior of a mixer, using a resistive diode, can in general be represented by means of an equivalent circuit consisting of two transducers connected in cascade. The first of these two transducers transforms the input signals into amplitude modidations; the seco?id is an AM detector which transforms these amplitude modulations into output signals. An important feature of this equivalent circuit is that it gives the dependence of the conversion loss upon certain important mixer parameters. We also show that extremely low (
