Abrupt Junction Varactor Diode Ceramic Package

The SMV1493 and SMV1494 bare die and hermetic packaged silicon abrupt junction varactor diodes are designed for use in VCOs requiring tight capacitance tolerances. The low resistance of these varactors makes them appropriate for high Q resonators in wireless system VCOs from RF to beyond 56 GHz.

Features

  • High frequency to beyond 56 GHz
  • Low series resistance for low phase noise
  • Multiple chip and hermetic packages
  • Lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020
  • SPICE models are provided
