Attenuators

An attenuator is an electronic device for reducing the strength of an audio or radio signal. The ATI-290M-20-SMA-02 is a digital precision step attenuator. It is frequently used in radio frequency signal measurements.

Application Field

The ATI-290M-20-SMA-02 is primarily used for attenuation of radio frequency signals. It is suitable for use in laboratory and field applications such as low-noise amplifier calibrations, signal level measurements, and antenna pattern measurements. The device also has applications in wireless communications, manufacturing test systems, and defense-related tests. Its high precision allows it to be used in conditions where high accuracy is required.

Working Principle

The ATI-290M-20-SMA-02 functions by allowing two electrodes to interact with each other within an area of electrically conducting material, known as a magnetron. This produces an electrical field, which is then used to control the attenuation of radio frequency signals. A separate control circuit is used to adjust the level of attenuation required.

The magnetron is designed to produce a high voltage, which allows it to generate a strong magnetic field. This field is then used to control the electrodes, resulting in the radio frequency signals being attenuated to a predetermined level. The control circuit is designed to allow the level of attenuation to be adjusted with precision.

The ATI-290M-20-SMA-02 also includes various external components, including capacitors, inductors, and resistors. These components are used to monitor the amplifier’s performance and suitable for monitoring power supplies.

Conclusion

The ATI-290M-20-SMA-02 is one of the most popular digital precision step attenuators. It is suitable for use in a wide range of applications, such as low-noise amplifier calibrations, signal level measurements, and antenna pattern measurements. The device uses a magnetron to control the level of attenuation. Its external components are used to monitor the amplifier\'s performance. With its high precision and accuracy, the ATI-290M-20-SMA-02 is an excellent choice for attenuating radio frequency signals.
