Schottky diodes optimized for operation in varactor mode
ACST offers several types of Schottky diodes, optimized for operation in varactor mode at mm-waves and THz frequencies.
They differ in structure layout, number of anodes, dedicated frequency range, and mounting approach. ACST varactor diodes feature high breakdown voltage, low series resistance, and maximal modulation ratio of the junction capacitance.
These parameters make them best suited for building frequency multipliers (frequency up-conversion) but they are also suited for other applications like phase shifters, RF resistors, switches, power detectors, etc.
