Description
M/A-COM’s MA4ST200 series is a 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 Q and low voltage operation. Each varactor type has a Q
greater than 400 at -2 V.

Applications
The MA4ST200 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 for use in the wireless communications up to the
2.4 GHz band. Applications include VCOs and voltage tuned
filters.

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,
MA4ST230-1141 specifies the MA4ST230 varactor in the
SOD-323 package. The model number indicated is for a single
varactor. Common cathode pairs are available in SOT-23
package, and are specified by adding “CK” to the end of the
model number. For example MA4ST230CK-287 specifies the
MA4ST230 varactor in common cathode pairs.
