DESCRIPTION
The combination of high Q and low surface noise results
in low FM noise in VCO applications. They are particu-

reliability, low leakage current, and very low surface
noise. They offer Q values well above ion-implanted
hyperabrupt diodes.
The specifications below apply to chips, or to chips
mounted on carriers. Although these chips can be pro-
vided in any of our standard packages, this is not recom-
mended for the lower capacitance diodes, because the
parallel parasitic capacitance of the package degrades
linearity at high bias voltages.
APPLICATIONS
The GC15000 series of frequency-linear tuning varactors
are used in VCO’s, filters, amplifiers and modulators for
wide band tuning through Ku band. The frequency linear
characteristics allow over one octave linear tuning in
