Varactor Diode Modulator is a semi-conductor diode having a variable junction capacitance. The variation is achieved by applying a reverse bias. The junction capacitance of varactor diode varies linearly with applied voltage. The disadvantage of this varactor diode modulator is that is uses a two terminal device. Thus it is used mostly in automatic frequency control and remote tuning. How can I resolve frequency control?
