TOC 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 ...
