The development of frequency multipliers based on GaAs Schottky barrier diodes have become a practical solution to implement power sources at millimeter and sub-millimeter wave regions. At these frequencies, parasitic effects introduced by the diode package elements cannot be neglected, and an accurate modeling of it is necessary. A single-anode designâ€¦ (More)

Frequency mixers and multipliers are the key for heterodyne active imaging systems. In millimeter wave band, developing cost efficient devices based on commercially available GaAs Schottky diodes requires a detailed approach, far from the simple lumped element models.
