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.

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.
 Harmonics Generation
 Local Oscillators
 Frequency Synthesizers
 Up Converters
