SMV1213 Series

Hyperabrupt 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.



SMV1213 Series includes SMV1213-079LF, SMV1213-001LF, SMV1213-004LF and SMV1213-040LF.
