Optimal operation modes of low cost RF power diode detector on multi-tone signals

The results of theoretical and experimental researches on optimizing the RF diode power detector parameters to achieve the maximum dynamic range of quadratic detection of two-tone microwave signals in a wide frequency band are presented. The detector is based on low-barrier Schottky diode with zero bias. Optimum values of the detector load resistance, the diode saturation current, and corresponding to the specified regime the detector dynamic range are determined.
