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.
