SMV1247011

The surface mount plastic varactor diodes  SMV1247001 to SMV1255001 are designed for RF and Microwave applications in VCOs, electronically tunable filters and matching networks. Package offerings include the SOT23 and the small footprint SOD323 package. Alpha offers a comprehensive capability in capacitance values,package options and voltage ratings all aggressively priced for high volume commercial applications.

The SMV1247001 to SMV1255001 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 SMV1247001 to SMV1255001 may be employed in a backtoback 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 SOT23 package is typically 1.5 nH for each junction. Employing a common cathode SOT23 with the SMV1247001 to SMV1255001 varactors junctions connected in parallel reduces the inductance to approximately 0.9 nH. The inductance of a varactor in the SOD323 package is approximately 1.5 nH.
