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.
1. Operation of this device above any one of these parameters
may cause permanent damage.
2. Please refer to application note M538 for surface mounting
instructions

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.
