Description
The MA4ST300 series are ion-implanted, hy-
perabrupt junction, silicon tuning varactors in SC79,
SC70 3LD, and SOD-323 surface mount packages.
This series of varactors is designed for high capaci-
tance 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 applica-
tions where the supply voltage is limited to 5 volts or
less. These varactors have been specifically de-
signed to cover wireless application bands up to the
2.4 GHz WLAN band. Applications include VCOs
and voltage tuned filters.
