Variable capacitance devices, also known as varicaps or varactors, are semiconductor diodes designed to provide a dependable, adjustable capacitance without the necessary manual adjustment. ZC836ATC Varactor Diodes are primarily used in frequency control applications, as well as providing voltage-controlled amplification in some higher frequency applications. The ZC836ATC is ideally suited for 5 GHz, near Ultisound, and beyond type applications, it is also ideal for frequency control in small PLL.

The ZC836ATC Varactor Diode is made up of a junction p-n, where the p-n portion is formed by an n-type and a p-type material. The anode of the diode is connected to the n-type region, while the cathode is connected to the p-type region. The junction includes an oxide layer, which allows the charge carriers to flow between the p-type and n-type regions.

The ZC836ATC Varactor Diodes can be used in a variety of applications where capacitance tuning is needed. In frequency control applications, such as satellite communication and cellular phones, the ZC836ATC can be used to tuning the designed frequency to thereby obtain precise frequency operation. The ZC836ATC diode is also used in applications such as high frequency amplifiers, mixers, oscillators and antennas.

The working principle of the body (the semiconductor junction) of the varactor diode is simple. When a small reverse bias is applied to the junction, the concentration of holes in the n-type region, and the concentration of electrons in the p-type region increases, thus forming a rectifying semiconductor junction. The thickness of the depletion layers in the junction varies with the degree of the reverse bias, which change the capacitance of the junction, thus varying the amount of stored charge on either side of the junction.

The ZC836ATC Varactor Diode is a cost-effective and reliable solution for applications that require frequency control. The diode offers high capacitance ratio variance due to a fixed ratio of reverse bias to p-n junction capacitance. As a result, the ZC836ATC has high frequency response due to its low series resistance and minimal harmonic distortion. Furthermore, the device is highly reliable and features excellent repeatability, low noise, and excellent temperature stability.

In sum, the ZC836ATC Varactor Diode is well suited for applications such as frequency control, high frequency amplifiers, antennas, microwave amplifiers, and mixers. As its low series resistance and minimal harmonic distortion ensures highest quality performance, this device is a cost-effective and reliable solution for applications requiring frequency control.
