Tuning Varactors

FREQUENCY LINEAR TUNING VARACTORS

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 particu-

larly useful in modulated VCO’s because of their con-

stant sensitivity, and high modulation rate capability.

DESCRIPTION

A Frequency Linear Tuning Varactor (FLTVAR) is a sili-

con epitaxial mesa device, designed to provide wide-

band Linear Tuning in VCO and filter applications.

ELECTRICAL SPECIFICATIONS: T =25°C

These diodes feature thermal oxide passivation for high

reliability, low leakage current, and very 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 pro-

vided in any of our standard packages, this is not recom-

mended for the lower capacitance diodes, because the

parallel parasitic capacitance of the package degrades

linearity at high bias voltages.

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
