ATT-290M-30-SMA-02 Attenuators

An ATT-290M-30-SMA-02 attenuator is a device used to reduce the amplitude of a signal. It is typically configured in the form of a two-port network, with input and output ports that are connected to the signal source and destination. The device is a passive component, which means that it does not require a power source in order to work, and its operation relies solely on the signal passing through it.ATT-290M-30-SMA-02 attenuators are widely used in a variety of applications where power levels or signal levels need to be lowered to a safe level for further processing or to prevent interference, while still preserving the necessary characteristics of the signal.

Application Field

ATT-290M-30-SMA-02 attenuators are mainly used in radio frequency engineering, such as in the fields of cellular telecommunications, satellites, GPS, broadcast television and radio, and navigation systems. They are also widely used in electronic warfare, avionics, and aerospace applications, and in medical instrumentation for MRI and CAT scans.The first and most common application is in cellular telephone communication. The transmission power of mobile phones is limited by regulations, requiring attenuators to be used to continually adjust transmitted radio frequency signals so that they comply with established standards.Another application of attenuators is in flight control systems, where their use allows manual or automatic control of aircraft flight surfaces in order to maintain the required shape and condition of the aircraft’s airframe. The attenuator also ensures that the aircraft can remain under control during turbulent air conditions.

Working Principle

The ATT-290M-30-SMA-02 attenuator is an electronic device designed to reduce the amplitude of the signal passing through it. It is composed of two ports, one for the signal input and one for signal output.The attenuator operates by having the incoming signal pass through a series of resistors, which absorb a portion of the signal’s energy and reduce its amplitude. In order to adjust the amount of attenuation, the size of the resistors and the number of resistors used can be changed.Due to the passive nature of the device, no external power supply is necessary and the only power source is the signal itself. The proper use of the device depends heavily on the type of the application and the type of signal being attenuated.ATT-290M-30-SMA-02 attenuators are also able to provide wide attenuation ranges with wide dynamic range, low overall power dissipation, and very low distortion levels, making them suitable for applications requiring precise signal control.

Conclusion

The ATT-290M-30-SMA-02 attenuator is a widely used device in many applications. Its primary function is to reduce the amplitude of the incoming signal while preserving the necessary characteristics of the signal. The device operates without the need for an external power supply, relying solely on the signal that passes through it. The attenuator is mainly used in radio frequency engineering, avionics, electronic warfare, aerospace applications, and medical instrumentation. The device is composed of two ports and operates by having the incoming signal pass through a series of resistors, which absorb a portion of the signal’s energy and reduce its amplitude. The size of the resistors and the number of resistors used can be changed to adjust the amount of attenuation.
