Description

The

MA4ST300

series

are

ion-implanted,

hy-

perabrupt junction, silicon tuning varactors in SOT-

23, SOT-323, and SOD-323 surface mount pack-

ages. 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 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.
