Description

The MAVR-000079 - 83 series of silicon hyperabrupt

junction tuning varactors is produced with ion

implantation

and

advanced

epitaxial

growth

techniques. These diodes have thermal oxide

passivation, and feature very high capacitance ratio

and quality factor. They are well suited for use from

the sub-HF through UHF frequency range. The

standard capacitance tolerance is ±10%, with tighter

tolerances available. Capacitance matching at one

or more bias voltages is also available. These

diodes are offered with standard Sn/Pb plating, as

well as 100% matte Sn plating.

Applications

This series of hyperabrupt junction tuning varactors

is suggested for usage where a large frequency

change is required with only a small change in

tuning voltage. This series is appropriate for usage

in wide band voltage controlled oscillators and

voltage controlled filters which require the largest

rate of change of capacitance with voltage. The

large change in capacitance from 1 to 8 volts makes

them very attractive for battery operated or other

systems with limited available control voltage. This

varactor series can be used in VCO’s and VTF’s

from approximately 100 KHz through the UHF

frequency band.
