The MAVR-000080 - 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 hyper abrupt 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.
