VARACTOR DIODES

HF/VHF Super Hyperabrupt Junction

RoHS Compliant

DESCRIPTION

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

. Octave Tuning Range

. Ultrahigh Q

. Tough MIL-Spec Glass

They are also available in closely matched sets as well as tight Ct

tolerance options. Consult the factory for details.

Passivation

. Precision Grown Junction Epitaxy

. Available with 5% Tolerance C_T

. ROHS Compliant ¹

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.

APPLICATIONS/BENEFITS

. HV-VHF VCO’s

. TCXOs and VCXOs

. Analog phase shifters

. Frequency Modulators

. Preselectors
