Description
The MA4ST079 through MA4ST083 series of silicon
hyperabrupt junction tuning varactors is produced with
ion implantation and advanced epitaxial growth tech-
niques. 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 toler-
ance is ±10%, with tighter tolerances available.
Capacitance matching at one or more bias voltages is
also available.
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 voltage
controlled oscillators and voltage controlled lters 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.
The MA4ST079 through MA4ST083 family can be used in
VCOs and VTFs from approximately 100 KHz through the
UHF frequency band.
