ATT-0291-10-HEX-02

Attenuators are devices used for reducing the power of an electrical signal, often in order to minimize interference or noise. The ATT-0291-10-HEX-02 is one example of an attenuator that uses a stepped attenuator topology in order to meet stringent requirements for accuracy and repeatability in a variety of applications.

The ATT-0291-10-HEX-02 is a tiny, low-cost, three-terminal device. It offers an input resistance of 800 ohms and a maximum attenuation of 10 decibels (dB). The device features a 6 dB/step range, providing 0 to 10 dB of attenuation in 6 dB increments. This makes it suitable for applications such as audio signal attenuation, noise correction and protection circuits, as well as the accurate measurement of RF signals.

The ATT-0291-10-HEX-02 utilizes a charged switched-capacitor (CSC) topology for achieving high accuracy over a wide range of conditions. This topology employs a thermally stable, optically isolated monolithic substrate that contains the accurate signal switching components. The ATT-0291-10-HEX-02 is thus able to provide excellent linearity and repeatability for both analog and digital RF signal attenuation requirements.

Moreover, the ATT-0291-10-HEX-02 is highly reliable and capable of operating over a wide temperature range (-40℃ to +85℃). It also meets strict EMC requirements, such as those of EN 55022 Class B. This makes it suitable for many industrial applications, such as telecommunications and cell-phone base stations.

In terms of working principle, the ATT-0291-10-HEX-02 utilizes a topology of charged switched-capacitors (CSC). It is constructed with an output terminal, an electrical input terminal, and an electrical antistatic terminal. An antistatic terminal is used to reduce the possibility of undesirable static charges from developing on the attenuator\'s active components. This is critical for accuracy and repeatability, as static charges on the active components can cause errors in the attenuation measurements.

The operation of the ATT-0291-10-HEX-02 is based on the use of a switched-capacitor topology. A set of capacitors is switched according to an input signal in order to achieve a desired output voltage level. The device can attenuate signal voltages over the range of 0 to 10 dB. Additionally, the ATT-0291-10-HEX-02 employs a constant-impedance output that ensures maximum signal fidelity and absolute accuracy.

In conclusion, the ATT-0291-10-HEX-02 is a tiny, low-cost device that enables accurate attenuation of analog and digital RF signals. It provides excellent linearity and repeatability in a wide range of applications, including audio signal attenuation, noise correction and protection circuits, and RF signal measurement. The device is highly reliable and capable of operating over a wide temperature range (-40℃ to +85℃), providing excellent performance and repeatability. The ATT-0291-10-HEX-02 is thus an ideal choice for industrial applications that require stringent requirements for accuracy and repeatability.
