Description
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.
Table 1 describes the various packages and markings of the SMV123x varactors.
