Diodes - Variable Capacitance (Varicaps, Varactors)

Diodes – Variable Capacitance (Varicaps, Varactors) are electronic components that combine the functions of a diode and a variable capacitor. They have a capacitance that can be changed by applying a voltage or current signal, allowing for precise control over the flow of electrical current. These devices are commonly used in high-frequency applications such as radio frequency (RF) circuits, microwave amplifiers, and digital logic circuits. They offer excellent linearity, low power consumption, and fast switching times, making them ideal for use in modern communication systems.
