SMV1236 Series
Hyberabrupt Junction Tuning Varactor

The SMV123x series of silicon hyperabrupt junction varactor diodes are designed for use in Voltage Controlled Oscillators (VCOs) with a low tuning voltage operation. The low resistance of these varactors makes them appropriate for high-Q resonators in wireless system VCOs to frequencies over 10 GHz. This family of varactors is characterized for capacitance and resistance over temperature.

Features

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