VARACTOR DIODES
Microwave Hyperabrupt Junction
RoHS Compliant
DESCRIPTION
The KV2100 series of microwave hyperabrupt varactor diodes offers octave
tuning through 8 GHz. High reliability passivated construction, insures
excellent VCO settling time and post tuning drift characteristics. As with
their UHF counterparts, straight-line tuning can be achieved over a mid
voltage bias range. They are available in a wide range of package styles
and configurations including matched sets with tighter tolerances. As is the
case with all microwave applications, chip devices (style 00) are
recommended for best wide bandwidth and highest frequency
performance. When ordering specify the desired case style by adding its
number as a suffix to the basic model number. Some limitations apply.
Consult factory for details.

APPLICATIONS
Ultrahigh Q and excellent large signal handling capabilities, along with a
greater than 4 to 1 capacitance ratio, is obtained by tuning from 4 to 20
volts of reverse bias.
These products are ideal for linear, wide deviation tuning of VCXO/TCXO’S
and frequency modulators results when these diodes are tuned over a 3 to
8 volt bias range.
