SMV1212 Series

Hyperabrupt Junction Tuning Varactor


Please note: SMV1212 Series is being discontinued and is not recommended for new designs.

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.

SMV1212 Series Series includes SMV1212-001LF and SMV1212-079LF.
