Attenuators

An attenuator is a device used to reduce the strength of a signal. In electrical engineering, an attenuator is a device that consumes energy from a signal without changing its waveform, in other words; it reduces the amplitude of the signal without changing its frequency. In other words, an attenuator is a device used to reduce the power of an electric signal.

ATT-0219-13-NNN-02 Application Field And Working Principle

The ATT-0219-13-NNN-02 is a high-frequency wideband MMIC attenuator designed for applications in the 3.0 to 6.0 GHz frequency range. The device consists of an input buffer, a variable attenuator, and an output buffer. A voltage-controlled resistor is used to produce attenuation, providing wide dynamic range and maintaining linearity with low distortion. The device has a small footprint of only 5 mm2 and operates from a single +3V DC supply voltage and requires no external components for operation.

The device has excellent insertion loss between 6 and 18.5 dB, stability and repeatability across the entire operating range of 3 to 6 GHz. The device also has excellent return loss. It has sufficient linearity and attenuation across the entire operating range for applications that require high linearity and low distortion.

The ATT-0219-13-NNN-02 attenuator is designed to be used in a wide variety of applications such as digital subscriber line (DSL) modems, cable modems, Wi-Fi, Wide Area Network (WAN), microwave radio, satellite and cellular systems, military, and other applications that require wide dynamic and linearity performance. It is also useful for applications that require wide dynamic range, high linearity, and distortion free signal transmission with low power consumption.

The working principle of this device is very simple. The device consists of a voltage-controlled resistor (VCR) whose resistance is varied by applying a control voltage to it. This control voltage varies the resistance of the VCR which in turn varies the attenuation level of the signal applied to the device. The input and output matching networks are optimized to provide good input and output return loss performance and broadband operation.

The device is able to offer excellent linearity and distortion at the same time with very low power consumption. The wide dynamic range and linearity makes this device ideal for applications such as DSL, cable modems, Wi-Fi, WAN and microwave radio.

In conclusion, the ATT-0219-13-NNN-02 is a high frequency wideband MMIC attenuator designed for applications in the 3.0 to 6.0 GHz frequency range. The device offers excellent insertion loss, stability, repeatability and return loss across the entire operating range and is ideal for applications that require high linearity and low distortion. The device is also suitable for applications that require a wide dynamic range, high linearity, and distortion free signal transmission with low power consumption.
