Introduction

Diodes – Variable Capacitance (Varicaps, Varactors) is a type of semiconductor device which can be used for various applications, one of them being the ZMV835BTC. This device is a high performance Varicap diode, perfectly suited for any type of RF and IF application requiring a wide range of modulation.

Overview

The ZMV835BTC diode is a Lambertian-shaped Varicap diode which is fabricated using a planar design. The AC signal used for modulating the device is applied to the anode, and the other electrodes are connected to the cathode and the gate, respectively. The varicap diode is made up of two sections; one section consists of a varicap dielectric while the other is composed of two conductive junctions. The combination of these two sections gives it its distinctive feature of having both low DC and AC leakage current.

Application Fields

The ZMV835BTC is mainly used in modulated signal applications as it offers wide range modulation and superior linearity. Examples of some of the application fields it is suited for include tunable FM transmitters, frequency synthesisers, and Bluetooth radio receivers. Other applications such as wireless equipment, high-dynamic range amplifiers, and high-grade receivers could also benefit from the use of this device.

Working Principle

The ZMV835BTC operates using the principle of variable capacitance. It is capable of changing the capacitance of its gate junction when an AC voltage is applied to it. The capacitance is regulated by the voltage applied and the stored charge in the gate junction. When a positive voltage is applied, the capacitance increases and when a negative voltage is applied, the capacitance decreases. As a result, this device can provide an extra degree of modulation.

Conclusion

The ZMV835BTC is an excellent Varicap diode which offers superior linearity and features a wide range of modulation. This makes it the perfect choice for any application requiring RF and IF modulation. Its wide application fields and working principle make it ideal for use in various electronic devices and systems.
