Description and Applications
M/A-COM’s MA4ST2000 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 for low
battery voltage operation. It is efficient for wide band tun-
ing and low phase noise application where the supply volt-
age is limited to 5 volts or less. Varactors in this series
have a typical 18:1 capacitance ratio between 0.1 V and
4.7 V and a 12:1 ratio between 0.1 V and 2.7 V. The
Varactors are offered as Singles in both SC-79 and SOD-
323 configurations with Common Cathode version offered
in a SC-70, 3 Lead. These diodes are offered with stan-
dard 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.
