Analysis on the linearity of the balanced diode mixer driven by the square wave LO

In this paper, analysis on the linearity of the balanced diode mixer driven by the square wave LO is described For the objective, the circuit analysis based on the diode model with the ideal switch and the resistor is indicated and the derived formula clarifies the linear operation under some conditions. Furthermore the normalized output powers and the third order distortion of the mixer are demonstrated with the square wave LO and the sinusoidal LO. This analytical result and experiments confirm the high linear characteristics of the balanced diode mixer driven by the square wave LO.
