VARACTOR DIODES
HF/VHF/UHF Hyperabrupt Junction
RoHS Compliant
DESCRIPTION
These families of hyperabrupt junction RF varactor diodes feature
computer controlled grown junction epitaxy which provides extraordinary
consistency and the highest Q available in a 22 Volt hyperabrupt varactor.
These series give the designer a full capacitance range of 10 to 500 pF at 3
or 4 volts of bias, depending on product series. They allow octave tuning of
LC tanks through 500 MHz. With a reduced 1.5 to 1 frequency ratio,
straight-line-frequency tuning over a 3 to 8 volt tuning range is possible.
Ultrahigh Q and excellent large signal handling capabilities, along with a 2
to 1 capacitance ratio, is obtained by tuning from 9 to 20 volts of reverse
bias. Linear, wide deviation tuning of VCXO/TCXO’S and frequency
modulators also results when these diodes are tuned over a 3 to 8 volt bias
range.
Closely matched sets of all HF-VHF diodes are available along with “A”
suffix versions having ±5% capacitance tolerance at 3 or 4 volts of reverse
bias depending on series selected.

APPLICATIONS
These families of hyperabrupt varactors are ideal for wide bandwidth
VCOs. They also provide excellent performance in frequency modulators,
voltage variable filters, analog phase shifters, TCXOs and VCXOs.
