The BB187LX,315 is a type of diode designed to provide variable capacitance – also known as varicaps, varactors, or tuning diodes – and is widely used in oscillator and tuning applications. By altering the applied voltage, the diode\'s capacitance can change, allowing the user to both control and measure it. This makes the BB187LX,315 the perfect choice for any application that requires stable, accurate capacitance over a wide range of frequencies.

A Varactor diode is a two-terminal, reverse-bias diode. It is named for the PN junction between its two terminals, which acts like an infinite capacitor. Unlike a traditional capacitor, which has a fixed capacitance and can hold a finite amount of charge, a Varactor diode can adjust its capacitance in response to an applied voltage. This makes it incredibly useful in tuning applications, where the capacitance of the diode can be altered to obtain the desired frequency.

The BB187LX,315 is designed to provide variable capacitance in a wide range of frequency operations, from low-to-high-frequency. This is achieved through a combination of a PN junction, a large widthN well, and an advanced silicon processing technology. The main physical elements of the diode are three electrodes – an anode, a cathode, and a gate. The anode-to-gate voltage creates an electric field between the anode and the gate, resulting in the diode\'s capacitance changing. The diode has a typical capacitance range of 0-10pF and can operate at temperatures from -65°C to +150°C.

The most common usage for a BB187LX,315 is as a capacitor in RF oscillator and frequency control applications. By changing the applied voltage, the diode\'s capacitance can be adjusted. This allows the user to adjust the operating frequency of the oscillator, allowing for fine-tuning or the selection of a frequency range. The diode can also be used in radio circuits and AM/FM radio receivers to help select a specific frequency. It can also be used in mixers and modulators, as well as in audio applications.

The BB187LX,315 is the perfect choice for any application that requires a reliable, accurate varactor diode with varying capacitance. Its design allows for a wide range of temperatures and frequencies, making it suitable for a wide range of applications. Its three-electrode design also provides enhanced flexibility for controlling the diode\'s capacitance, allowing users to adjust the capacitance with minimal effort. Additionally, the diode\'s flexibility means it is also suitable for many RF tuning applications.
