VARACTOR DIODES
HF/VHF/UHF Hyperabrupt Junction
®

RoHS Compliant
DESCRIPTION
KEY FEATURES
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.
. Available as packaged devices or
as chips for hybrid applications
. Octave Tuning Range
. Ultrahigh Q
. Available with 5% Tolerance CT
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
APPLICATIONS/BENEFITS
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.
. Values cover the entire HF / VHV
/ UHF spectrum;
. Highest Q / lowest VCO phase
noise
. Tough MIL-Spec SiO2 passivation
. Dozens of package outlines
