The GC3200 series of harmonic generator varactors uses a single epitaxial silicon die. Strict material and process controls result in high reproducibility. A unique silicon dioxide passivation process assures greater stability, reliability and low leakage currents at high temperatures. This series of diodes is available in a wide selection of capacitance values, breakdown voltages, transition times and cutoff frequencies for optimum circuit design. These devices have the best efficiencies and thermal dissipation available in single chip multiplier varactors.
