Diodes – Variable Capacitance (Varicaps, Varactors) are a type of electrical component that is used in a variety of applications, such as radio-frequency signal detection, frequency synthesis, and pulse shaping. BB198,115 is one example of such a diode which has become known for its high performance and reliability in these applications.

General Design Overview

BB198,115 is a variable capacitance diode which is designed to regulate current and voltage flow. The device is made up of an anode and cathode, which are connected via a sealed, gas-filled cavity. The diode utilizes a single junction gate to alter the capacitance within the cavity according to the applied voltage. This capability allows the device to be used in a wide variety of frequency-varying applications, such as signal detection and frequency synthesis.

Construction and Working Principle

BB198,115 is constructed using a monolithic junction gate, which is mounted on a thin film of glass insulator and placed between two electrodes. The electrodes are then connected to an anode and cathode which are enclosed within an air-tight enclosure. The cavity between the anode and cathode is filled with an inert gas, such as nitrogen.

When the diode is subjected to a voltage, the gas within the cavity becomes ionized, which produces a varying electric field across the electrodes. This electric field causes a change in the capacitance of the device, which in turn controls the flow of current flowing between the electrodes. This allows the device to effectively regulate current and voltage flows for a variety of frequency-sensitive applications.
