Description
M/A-COM’s MA4ST200 series is a ion-implanted,
hyperabrupt junction, silicon tuning varactors in
SOT-23, SC70 3LD, 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. These diodes
are offered with standard Sn/Pb plating , as well as
100% matte Sn plating on our RoHS compliant
equivalent devices.
Applications
The MA4ST200 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 for use in the wireless communications up to
the 2.4 GHz band. Applications include VCOs and
voltage tuned filters.
