Varactor tuning diodes
The 3022 series of high-ratio, hyperabrupt, varactor tuning diodes from Knox Semiconductor was designed to control crystal oscillator frequency with a DC-bias voltage. The capacitance variation of the diode (C/V) is approximately 10:1 over the voltage range of 0.3 to 4.0 V; a particular C/V specification depends on which one of four part numbers are chosen. The highly reproducible ion-implanted structure of the diode offers a high-capacitance swing, linear characteristics of the capacitance versus voltage variation, and uniform capacitance versus temperature coefficient. The diodes are available in industry-standard packages such as the SOT-23, SOD-323, and the subminiature SOD-523, as well as in chip form.
