GC3202 – GC3208 TM POWER GENERATION Harmonics Generator Varactors ® RoHS Compliant KEY FEATURES 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. X2 Through X20 Harmonics Unless otherwise specified, capacitance will be within the range shown for each type. A capacitance tolerance of ±10% is available at an additional charge. Diodes can be optimized for custom electrical or mechanical specifications. Custom parameters for capacitance, voltage, transition time, cutoff frequency, etc. are available upon request. Generation Excellent Efficiency High Output Power 1 RoHS Compliant 1 The GC3200 Series of products are supplied with a RoHS complaint Gold finish. www.MICROSEMI.com DESCRIPTION All specifications shown above are based on the style 30 package, except for GC3202 and GC3203, which are based on the style 20 package. These latter two devices are available only in case styles 20 or 55 due to die size. Consult factory for availability. A complete list of case styles available along with dimensions and package parasitics are available at www.microsemi.com. The cathode is the heat sink end of each package. Diode chips, alone or mounted on carriers with gold wire/ribbon leads are also available. APPLICATIONS APPLICATIONS/BENEFITS The GC3200 series multiplier varactors can be used for all orders of multiplication from X2 through X20. They are used primarily in low harmonic order, high efficiency, high power applications. They are used in narrow and wide bandwidth frequency generator chains for all multiplication stages. Other applications include: voltage controlled oscillators, frequency synthesizers and up converters.
