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.
