【 Weak current College 】 varactor diodes main parameters 】

① high reverse voltage VR: refers to the increase in both ends of the capacitance diode reverse voltage must not exceed the allowed values of voltage.
② reverse Breakdown voltage VB. : Subject to reverse voltage, the voltage variable capacitance diode breakdown.

③ junction capacitance C: it refers to a specific anti bias, varactor diodes internal pn junction capacitance.

④ junction capacitance range: operating voltage range of capacitance ranges.

⑤ Capacitance ratio: refers to the knot capacitance change maximum capacitance and capacitance ratio.

⑥ q-value: is the quality factor of varactor diodes, reflects on the circuit of energy consumption.
