VARACTOR DIODES
LOW COST 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 30 Volt hyperabrupt
varactor. These series give the designer a full capacitance range of 9 to
27.5 pF at 3V of bias. 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 can be 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/BENEFITS
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.
