Description
M/A-COM’s MA4ST1103-1141T is a highly
repeatable, ion-implanted, hyperabrupt silicon
tuning varactor in a cost effective surface
mount package. This varactor is designed for a
higher capacitance ratio, a higher tuning
voltage, with a respectable Q value for wider
band VCO applications.

Mounting Information
The illustration indicates the recommended
mounting
pad
configuration
for
the
SOD-323 package. 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.
