Description and Applications
M/A-COM’s MA4ST1300 series is a highly
repeatable, UHCVD/ion-implanted, hyperabrupt
silicon tuning varactor in a cost effective surface
mount package. This series of varactors is designed
for high capacitance ratio, and high Q for low battery
voltage operation. It is efficient for wide band tuning
and low phase noise application where the supply
voltage is limited to 5 volts or less. The varactors are
offered as singles in SC-79 and SOD-323 along with
a common cathode version offered in the SC-70, 3
Lead. These diodes are offered with standard Sn/Pb
plating , as well as 100% matte Sn plating on our
RoHs compliant equivalent devices.

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.
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.
Please refer to Application Note M538 for
surface mounting instructions.
