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.
