SMV1233 Series

Hyperabrupt 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.



SMV1233 Series includes SMV1233-079LF and SMV1233-040LF.
