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.
