Description
M/A-COM’s MA4ST200 series is a 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 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 applications where the supply voltage is limited to 5 volts or
less. These varactors have been specifically designed for use in the wireless communications up to
the 2.4 GHz band. Applications include VCOs and
voltage tuned filters.

Mounting Information
The illustration indicates the recommended
mounting
pad
configuration
for
the
SC-79, SOT-323 and SOD-323 packages. Solder
paste containing flux should be screened onto the
pads to a thickness of 0.005- 0.007 inches. The
plastic package is placed in position, firmly adhering
to the solder paste.
SC-79
0.020

Permanent attachment is performed by a reflow
soldering procedure during which the tab
temperature does not exceed +275 °C and the body
temperature does not exceed +250 °C, for standard
models and +260 °C for the RoHS compliant
devices.
These varactors are available in the three case
styles shown. When ordering, specify the desired
case style by adding the case designation (287 for
SOT-23, 1146 for SOT-323, 1141 for SOD-323) as a
suffix to the model number. For example,
MA4ST230-1141 specifies the MA4ST230 varactor
in the SOD-323 package. The model number
indicated is for a single varactor. Common cathode
pairs are available in SOT-23 package, and are
specified by adding “CK” to the end of the model
number. For example MA4ST230CK-287 specifies
the MA4ST230 varactor in common cathode pairs.

( After the Base P/N ) :
SC-79 : 12790T
SOD-323 : 11410T
SOT-323 : 1146FT
As example, the RoHS P/N for the Base P/N
MA4VR-000230 in SOD-323 is :
MAVR-000230-1146FT.
