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 pas-

sivation, 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 toler-

ances 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 on our RoHs compliant

equivalent devices.

Applications

The MA4ST079 through MA4ST083 series of hy-

perabrupt junction tuning varactors is suggested for

usage where a large frequency change is required

with only a small change in tuning voltage. This se-

ries is appropriate for usage in wide band voltage-

controlled oscillators and voltage controlled filters

which require the largest rate of change of capaci-

tance with voltage. The large change in capacitance

from 1 to 8 volts makes them very attractive for bat-

tery operated or other systems with limited available

control voltage. The MA4ST079 through MA4ST083

family can be used in VCOs and VTFs from approxi-

mately 100 KHz through the UHF frequency band.
