novar ackermann electrical components are varactor diodes, also known as "variable reactance diodes," which are made using the characteristic that the junction capacitance of a PN junction changes with the applied voltage when reverse-biased. As the reverse bias voltage increases, the junction capacitance decreases; conversely, the junction capacitance increases. The capacitance of a varactor diode is generally small, with a maximum value ranging from tens of pF to hundreds of pF. It is mainly used in high-frequency circuits for automatic tuning, frequency modulation, and phase adjustment, for example, as a variable capacitor in the tuning circuit of a television receiver. The main parameters are: zero-bias junction capacitance, zero-bias quality factor, reverse break
