Description
The MA4ST079 through MA4ST083 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 fre-
quency range. The standard capacitance tolerance is
±10%, with tighter tolerances available. Capacitance
matching at one or more bias voltages is also avail-
able.These diodes are offered with standard Sn/Pb plat-
ing , as well as 100% matte Sn plating on our RoHs com-
pliant equivalent devices.
Applications
The MA4ST079 through MA4ST083 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 voltagecontrolled oscillators and volt-
age 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
