Variable Capacitance (Varicaps, Varactors) diodes can be used to efficiently control the operating frequency in multiple applications. Their most common use is in communications technology, where these variable capacitance diodes are used to create variable frequency filters and mixers. SMV1273-079LF capacitors are part of a range of high performance diodes designed for the tunable RF filter applications.

SMV1273-079LF diodes are designed to meet the needs of a variety of RF and microwave applications, from low power, low voltage, to high power and high voltage. The varicap diode is a high speed, highly reliable and low insertion loss device for frequency tuning. It is ideally suited for the design and development of a range of bandwidth-intensive frequency hopping, phase and amplitude modulation radio systems, as well as an varied range of wireless and wired communication applications.

The working principle behind these devices is based on the movement of charge-carriers within the layer of a semiconductor material. By changing the thickness of a thin semiconductor layer, an electric field is created which changes the charges and causes the capacitance of the diode to vary. The amount of capacitance depends on the voltage applied over the diode. As the voltage to the diode increases, the capacitance of the diode also increases. The opposite is true when the voltage is decreased.

When used in RF applications, SMV1273-079LF diodes leverage their wide frequency range and their ability to produce low noise levels. They are used in resonance filters, VLF antenna systems, and microwave frequency agile systems.
