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. Plastic Packaged Surface Mount Varactor Diodes
