What are varactor or tuner diodes?
A varactor diode or varicap diode is a semiconductor diode that changes its junction capacitance significantly depending on the applied reverse bias voltage. Many semiconductor PN junction diodes are designed to exhibit specific electrical properties; the varactor diode or varicap diode is one such semiconductor specifically designed to exhibit unique junction capacitance characteristics. These types […]
