Description
The MA4ST300 series are ion-implanted, hyperabrupt junction,
silicon tuning varactors in SOT-23, SOT-323, and SOD-323
surface mount packages. This series of varactors is designed for
high capacitance ratio and low voltage operation. Each varactor
type has a better than 3:1 capacitance ratio between 0.5V and
3.0V.

Applications
The MA4ST300 series tuning varactors are useful for wide band
tuning and low phase noise applications where the supply voltage
is limited to 5 volts or less. These varactors have been specifi-
cally designed to cover wireless application bands up to the 2.4
GHz WLAN band. Applications include VCOs and voltage tuned
filters.

Ordering Information
Parameter
Ratings
These varactors are available in the three case styles shown.
When ordering, specify the desired case style by adding the case
designation (287 for SOT-23, 1146 for SOT-323, 1141 for
SOD-323) as a suffix to the model number. For example,
MA4ST330-1141 specifies the MA4ST330 varactor in the
SOD-323 package. The MA4ST320 is available in the SOT-23
and SOD-323 packages only. The model number indicated is
for a single varactor. The MA4ST330, 340 and 350 are avail-
able in common cathode pairs in the SOT-23 package, and are
specified by adding “CK” to the end of the model number. For
example MA4ST330CK-287 specifies the MA4ST330 varactor
in common cathode pairs.
