Description

The surface mount plastic varactor diodes are

designed for RF and Microwave applications in

VCOs, electronically tunable filters and matching

networks. Package offerings 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.

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.

Alpha’s hyperabrupt varactors are available in a wide

variety of tightly specified capacitance values and

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 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.
