Question

What is Varactor diode?????

Answer 1

A varactor diode is a P-N junction diode that changes its capaci- tance and the series resistance as the bias applied to the diode is varied. The property of capacitance change is utilized to achieve a change in the frequency and/or the phase of an electrical circuit.

Answer 2

A varactor diode is also known as tuning diode.varactor diode is a variable capacitor controlled by varying voltage.
