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 S n 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

Mounting Information

The illustration indicates the recommended

mounting pad configuration for the

SOT-23 package. Solder paste containing flux

should be screened onto the pads to a thickness

of 0.005- 0.007 inches. The plastic package is

placed in position, firmly adhering to the solder

paste.

Permanent attachment is performed by a reflow

soldering procedure during which the tab

temperature does not exceed +275 °C and the

body temperature does not exceed +250 °C, for

standard models and +260 °C for the RoHS

compliant devices.

Please refer to Application Note M538 for

surface mounting instructions.
