Attenuators

ATT-290M-01-SMA-02 attenuators are specialized devices designed for radio frequency (RF) applications. They reduce the input signal strength before passing it through other components in the circuit. This helps reduce distortion and protects delicate components from being overloaded. The ATT-290M-01-SMA-02 is a high-performance attenuator manufactured by Shenzhen Huajing that is designed specifically for use in communications and other telecommunications applications.

Application Field

The ATT-290M-01-SMA-02 are ideal for a wide variety of RF applications such as digital radio receivers, cellular bases stations, RADAR systems, radio frequency amplifiers, and transceivers. The attenuator also provides a reliable signal restoring function for video amplifiers and other RF links. It is also useful for automated test systems that require precise signal strength adjustments.

Working Principle

ATT-290M-01-SMA-02 attenuators are based on the principle of Ohm\'s law. It works by adjusting the resistance of a resistor network to reduce the level of the input signal. The input signal is applied to the attenuator while an adjustable resistor connected to an insulated power source allows the user to control the amount of attenuation required. The attenuator can be connected in series or in parallel with the circuit to reduce power loss. The power source can be non-regulated such as a battery or regulated such as a DC power supply.

The ATT-290M-01-SMA-02 attenuators offer an exceptional performance for low-loss, low-noise applications. The attenuator is designed using a square element pattern that minimizes reflections, which helps achieve flat frequency response and low step errors. The attenuator also features a multi-step control, allowing the user to set attenuation levels that are accurate to within 0.04 dB. This helps reduce signal leakage and crosstalk.

The ATT-290M-01-SMA-02 is designed to be easy to use and maintain. The attenuator is constructed using quality materials and components, making it highly reliable and durable. The attenuator comes with a protective shroud that helps protect the attenuator from dust and other external elements. The attenuator also comes with a status LED that indicates when the attenuator is ready for use. Furthermore, the attenuator has a wide operating temperature range, making it suitable for use in a variety of environment.

Conclusion

The ATT-290M-01-SMA-02 attenuator is a high-performance RF device that is designed for use in radio frequency applications. It provides precise attenuation control, allowing users to adjust the desired level of attenuation easily. The attenuator also features a multi-step control that helps minimize signal leakage and crosstalk. The attenuator is highly reliable, durable and easy to use and maintain. Therefore, it is ideal for use in digital radio receivers, cellular bases station, RADAR systems, radio frequency amplifiers and transceivers.
