VARACTOR DIODES
®
HF/VHF Super Hyperabrupt Junction
TM
RoHS Compliant
DESCRIPTION
These super hyperabrupt varactor diodes are ideal for tuning LC resonant
circuits from video frequencies through VHF with frequency ratios as high
as 4 to 1. They are also ideal for wide deviation voltage controlled
oscillators and voltage controlled crystal oscillators. Two volt capacitance
values range from 57 to 350 pF are offered in this designer-oriented family.
These diodes feature exceptionally large capacitance ratios, very high Q,
straight-line frequency performance over a 1.5 to 4 volt tuning range.
They are also available in closely matched sets as well as tight Ct
tolerance options. Consult the factory for details.
The standard Super Hyperabrupt series of devices meet RoHS
requirements per EU Directive 2002/95/EC, including the discrete chip
(style 00) and package styles 30 and 17. The standard axial device (style
11) is not RoHS compliant. Please consult the factory for ordering
information for the RoHS version of the 11 style package.
APPLICATIONS
Ultrahigh Q and excellent large signal handling capabilities, along with a
greater than 10 to 1 capacitance ratio, is obtained by tuning from 2 to 10
volts of reverse bias. These diodes are well suited for linear, wide deviation
tuning of VCXO/TCXO’S and frequency modulators as well as analog
phase shifters, receiver preselectors, and active antenna matching units.
