ATT-290F-05-SMA-02

Attenuators are commonly used devices in a variety of electrical applications. They provide an easy way to reduce the signal strength, which can be beneficial both in terms of protecting circuits from over-powering, and providing more dynamic signal control. One of the most popular models of attenuators is the ATT-290F-05-SMA-02, which is a variable series attenuator designed for surface-mount application to deliver a wide range of low-frequency signal reduction without adversely affecting the overall signal integrity.

Application Field

The ATT-290F-05-SMA-02 is designed to reduce the power of low-frequency signals, making it ideal for a number of applications, including automotive stereo systems, residential and commercial audio systems, telecom equipment, wireless receivers and transmitters, radio communication systems, control networks and more. It can also be used in conjunction with spectrum analyzers and tracking generators.

This model of attenuator is particularly useful when dealing with RF power issues, such as trying to contain a wide signal level within a circuit, or reducing interference levels that may exist in a given system. It is also useful for preventing audio distortion due to wide signal level swings in the amplifier or speaker.

Working Principle

The ATT-290F-05-SMA-02 operates by using a variable series of attenuators to reduce the level of the signal. Depending on the application, these attenuators can be cascaded in series or placed in parallel. The varying resistance of the resistors determine the amount of attenuation and in some cases, can be adjusted even after installation.

In most cases, the attenuator is designed to be used in conjunction with an input signal sensing device such as a voltage-controlled resistor or diode. This sensing device enables the attenuator to react to changes in the input signal level, thereby providing the most effective signal reduction.

The ATT-290F-05-SMA-02 is constructed from ceramic material which has excellent heat and electrical conductivity. It also features an isolation resistance of 10^12 ohms and allows for extended thermal ratings and long service life. The overall size and design of this model of attenuator makes it ideal for use in a wide range of applications.

Conclusion

The ATT-290F-05-SMA-02 variable series attenuator is an ideal choice for a variety of low-frequency attenuation purposes, such as reducing interference levels, preventing audio distortion or containing signal levels. Thanks to its construction from ceramic material, compact size and adjustable resistance, this model of attenuator provides superior performance and a long service life across a number of applications.
