SMV1212 Series
Hyberabrupt Junction Tuning Varactor

The SMV121x series of silicon hyperabrupt junction varactor diodes are designed for use in Voltage Controlled Oscillators (VCOs) with a low tuning voltage operation. This family of varactors is characterized for capacitance and resistance over temperature.

Features

  • High capacitance ratio: C1v/C4v = 5 typical
  • Packages rated MSL1, 260 °C per JEDEC J-STD-020
