D E SCRI PTI ON

A Frequency Linear Tuning Varactor (FLTVAR™) is a silicon

epitaxial mesa device, designed to provide wideband Linear Tuning

in VCO and filter applications.

These diodes feature superior passivation for high reliability, low

leakage current, and low surface noise. They offer Q values well

above ion-implanted hyperabrupt diodes.

The specifications below apply to chips, or to chips mounted on

carriers. Although these chips can be provided in any of our standard

packages, this is not recommended for the lower capacitance diodes,

because the parallel parasitic capacitance of the package degrades

linearity at high bias voltages.

This series of diodes meets RoHS requirements per EU Directive

2002/95/EC. The standard terminal finish is gold unless otherwise specified.

Consult the factory if you have special requirements.

APPLICATIONS

The GC15000 series of frequency-linear tuning varactors are used in

VCO’s, filters, amplifiers and modulators for wide band tuning through

Ku band. The frequency linear characteristics allow over one octave

linear tuning in suitable circuits, with no need for external

linearization.

The combination of high Q and low surface noise

results in low FM noise in VCO applications. They are particularly

useful in modulated VCO’s because of their constant sensitivity, and

high modulation rate capability.
