.Introduction
Diodes - Variable Capacitance (Varicaps, Varactors) are semiconductor devices often used to generate or regulate voltage, or to receive and detect radio frequency (RF) signals. This type of diode is also known as a Voltage Ramped Diode because it changes its capacitance when a ramping voltage is applied to it. Vari-cap diodes are also called Varicaps, Varactors, Voltage Ramped Capacitors, Tuning Diodes, or Variable Capacitance Diodes. The most common use of variable capacitance diodes is to control a circuit\'s resonant frequency, which is useful in applications such as radios and cellular telephones.
BB 664 E7902 Application Field and Working Principle
The BB 664 E7902 is a variable capacitance diode designed for use in applications such as radio tuning, frequency synthesis, voltage regulation, and signal receiving and detecting. This type of diode is also ideal for use in voltage regulation as it varies its capacitance in response to an applied control voltage. The BB 664 E7902 is available in both chip and surface mount packages and can handle up to 10V of operating voltage. The operating temperature range is -40°C to +85°C.
The BB 664 E7902 works by using a back-to-back pair of P-N junctions. With the application of an external DC voltage, the built-in electric field between the two junctions varies proportionally, thus changing the capacitance between the two electrodes. Due to the linearity of its response, the BB 664 E7902 is an ideal choice for AC/DC voltage regulation and signal adjustment.
Apart from AC/DC voltage regulation and signal adjustment, the BB 664 E7902 can also be used in frequency synthesis applications. The variable capacitance of this diode allows for the generation of a range of frequencies, making it ideal for the analysis and synthesis of frequency modulated signals. Furthermore, this diode can also be used for signal reception and detection. It is capable of adjusting the resonant frequency of an antenna to match that of the incoming RF signal thus allowing a receiver to more clearly detect and receive the signal.
Conclusion
In conclusion, the BB 664 E7902 is an ideal choice for Variable Capacitance (Varicaps, Varactors) applications. This diode can be used in AC/DC voltage regulation, signal adjustment, frequency synthesis, and the reception and detection of RF signals. With its linear response, this diode can easily generate frequencies as required and adjust the resonant frequency of an antenna to that of an incoming signal with great precision. The BB 664 E7902 is also available in both chip and surface mount packages making it suitable for use in a wide range of applications.
