ATT-0290-30-SMA-02

Attenuators

The ATT-0290-30-SMA-02 attenuator is a type of electronic component classified as an attenuator, which is a device used to reduce the magnitude of a signal without changing its wave shape. This particular device is compatible with SMA connectors and can operate at frequencies of up to 30GHz. Its impedance is nominally 50 Ω and its power rating is 0.5 Watts.

Application field

The ATT-0290-30-SMA-02 attenuator is mainly used in applications where the signal intensity must be reduced or adjusted, such as amplifiers, mixers, attenuators, comparators, and transmitters. It can be used in various fields, including radio communications, test and measurement, medical technology, military electronics, and radar systems, with a range of signal input and output levels.

Working principle

The attenuator works by applying a predictable amount of resistance to the signal, thus reducing its magnitude. It works by inserting a series resistor between the input and output, causing a voltage drop due to the resistance of the resistor. This results in the input signal being reduced in amplitude, or \'attenuated\'. This type of attenuator comes in fixed value versions, which maintain a pre-determined attenuation amount, as well as adjustable versions, where the amount of attenuation can be adjusted via a rotary or dial.

Conclusion

The ATT-0290-30-SMA-02 attenuator is a versatile device used to reduce signal strength in applications such as amplifiers, mixers, and transmitters. Its working principle is based on the insertion of a resistor between the input and output, causing a voltage drop and attenuating the signal according to the resistance value chosen.
