MICROSEMI KV1801

KV1401 – KV1801
VARACTOR DIODES
HF/VHF Super Hyperabrupt Junction
®
TM
RoHS Compliant
KEY FEATURES
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.
 Available as packaged devices or
as chips for hybrid applications
They are also available in closely matched sets as well as tight Ct
tolerance options. Consult the factory for details.
 Octave Tuning Range
 Ultrahigh Q
 Tough MIL-Spec Glass
Passivation
 Precision Grown Junction Epitaxy
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.
 Available with 5% Tolerance CT

DESCRIPTION
 ROHS Compliant 1
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.
APPLICATIONS/BENEFITS
 HV-VHF VCO’s
 TCXOs and VCXOs
 Analog phase shifters
 Frequency Modulators
 Preselectors
