Attenuators are electrical devices designed to increase signal attenuation, which is the reduction in signal amplitude and general signal power. The AT-902(40) attenuators are used for a variety of applications, providing the user with adjustable attenuation, temperature compensation, and bandwidth selection.

The AT-902(40) is a broadband, passive attenuator with an attenuation range of 0 to 40 dB. It is designed to provide notch-free, adjustable attenuation up to 40 dB and a fast rise time. The bandwidth of the AT-902(40) is fixed over the entire attenuation range, ensuring a consistent signal power throughout the range of operation.

The AT-902(40) is a versatile tool for many applications where fixed or variable attenuation is desired. In audio applications, the AT-902(40) is often used to reduce levels between speakers and amplifiers, or between microphones and mixers. In RF applications, the AT-902(40) is used to adjust the signal gain of a system to increase or decrease output power. The adjustable attenuation of the AT-902(40) also provides greater control over the signal to noise ratio and allows for easier system optimization.

The AT-902(40) is a wide band, portable, rugged attenuator that is designed for use in a variety of industries, including industrial, aerospace, automotive, telecommunications, and medical systems. Its wide temperature range makes it optimal for use in extreme environmental conditions.

The core of the AT-902(40) is based on a passive network composed of resistors and reverse-biased diodes. The overall attenuation of the device is determined by the ratio of the resistive components. The resistive circuitry is designed to provide low-frequency, low-loss attenuation across the entire attenuation range, while maintaining a high linearity of the attenuation slope. The reverse-biased diodes are used to provide a high reverse isolation and stable attenuation across temperature changes.

The AT-902(40) can be operated in either a fixed or adjustable mode. In fixed mode, the user sets the desired attenuation level and the repeater is triggered to emit a signal at the selected attenuation level. In adjustable mode, the user can use a control panel to adjust the attenuation up or down. The control panel is designed to provide the user with precise control over the selected attenuation level.

The AT-902(40) is ideal for applications that require manual or automatic adjustment of signal level. It is also suitable for use in dynamic range expansion, intermodulation distortion reduction, RF signal gain control, and noise reduction. It can be used in a variety of environments, including on-site RF testing, broadcast and recording, industrial machine control, and vehicle diagnostics. With its adjustable attenuation range and wide temperature range, the AT-902(40) is an indispensable tool for many applications.
