Description
The surface mount plastic varactor diodes are
designed for RF and Microwave applications in
VCOs, electronically tunable filters and matching
networks. Packageofferings include the SOT–23 and
the small footprint SOD–323 package. Alpha offers a
comprehensive capability in capacitance values,
package options and voltage ratings all aggressively
priced for high volume commercial applications.
high capacitance ratios. They are available as single
junctions and common cathode configurations where
they may be employed in a back–to–back orientation
to reduce distortion.
Alpha’s abrupt junction varactors are noted for
extremely high Q factor and are the preferred choice
in applications that require low phase noise and high
temperature stability.
The SMV1247–001 to SMV1255–001 varactors were
specifically designed for battery operated
applications where 3 to 5 volts is available. These
varactors have capacitance ratios of greater than 12
from 0.3 to 4.7 volts.
The inductance of the SOT–23 package is typically
1.5 nH for each junction. Employing a common
cathode SOT–23 with the varactor junctions
connected in parallel reduces the inductance to
approximately 0.9 nH. The inductance of a varactor
in the SOD–323 package is approximately 1.5 nH.
Alpha’s hyperabrupt varactors are available in a wide
variety of tightly specified capacitance values and
