Tuning Varactors
FREQUENCY LINEAR TUNING VARACTORS
DESCRIPTION
A Frequency Linear Tuning Varactor (FLTVAR)TM is a silicon epitaxial mesa device, designed to provide wideband Linear Tuning in VCO and filter applications.
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 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.
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.
