GC15001 – GC15013 TUNING DIODES Frequency Linear Tuning Varactors ® TM RoHS Compliant KEY FEATURES A Frequency Linear Tuning Varactor (FLTVAR™) is a silicon epitaxial mesa device, designed to provide wideband Linear Tuning in VCO and filter applications. Wideband Linear Tuning 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. Computer Controlled Grown 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. Octave Tuning 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. www.MICROSEMI.com DESCRIPTION Very Low Phase Noise Exceptional Q. Junction Epitaxy Functional through Ku Band 1 RoHS Compliant 1 Most products are supplied with a Gold finish and are suitable for RoHS complaint assembly. Consult factory for details. 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.
