Description
M/A-COM’s MA45400 series is a highly repeatable,
UHCVD/ion-implanted, abrupt silicon tuning varactor in a
cost effective surface mount package. This series of varac-
tors is designed for general purpose tuning in the HF to
UHF frequency bands. It is efficient for wide tuning across
a 0-30V range. These diodes are offered with standard Sn/
Pb plating , as well as 100% matte Sn plating on our RoHs
compliant equivalent devices.

Application
M/A-COM’s MA45400 series tuning varactor is useful for
tuning applications in the HF through UHF ranges. Appli-
cations include VCO’s and voltage tuned filters in radios,
cable TV tuners and test instruments where low cost and
excellent lot to lot repeatability are critical.

Mounting Information
The illustration indicates the recommended
mounting pad configuration for the
SOT-23 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.
