SMV1405 Series
Plastic Packaged Abrupt Junction Tuning Varactors

The SMV1405-SMV1430 group of silicon abrupt junction varactor diodes is designed for use in Voltage Controlled Oscillators (VCOs) requiring tight capacitance tolerances. The low resistance of these varactors makes them appropriate for high-Q resonators in wireless system VCOs to frequencies above 10 GHz. This family of varactors is characterized for capacitance over temperature.

Please note: SMV1405-074LF is being discontinued and is not recommended for new design.

Features

  • High Q
  • Low series resistance for low phase noise
  • Packages rated MSL1, 260 °C per JEDEC J-STD-020
