Attenuators are passive networks used to reduce the amplitude of an electrical signal while preserving the waveform. Attenuators come in many varieties – fixed or variable, linear or logarithmic – and are made in a variety of styles including wire-wound, radial-tapped, shunt, and SMT. The ATT-0444-02-HEX-02 is a two-port variable attenuator from RF Components. It is a high performance, low cost solution for changing the amplitude level of an electrical signal without altering its waveform.

ATT-0444-02-HEX-02 is an SMA connectorized, surface mountable, linear step attenuator. It features a two-port architecture with an RF signal path and dc control path. This attenuator is compliant with ANSI C63.11-2009 (Electrostatic Decay Test) and ANSI C63.4-2009 (60 V – 500 kHz ac De-embedding Test) specification. It can reduce the signal up to 25.5 dB without introducing any distortion.

ATT-0444-02-HEX-02\'s application field is mostly in the RF field, such as microwave radios and communications systems, satellite communications, and test and measurement equipment. It is designed to handle input signals from 2.4 GHzto 4.0 GHz and offers wide operating bandwidth of -20 dB to +6 dB over the frequency range. It\'s made of high performance gold-plated single-layer ceramic substrate with metal conductors.

The working principle of ATT-0444-02-HEX-02 is simple. The RF signal is fed to the RF “through” port. The signal entering at this port is split, routed, and recombined at the attenuator element. This attenuator element is biased by a dc voltage applied to the dc control input. The dc control voltage imposes an impedance shift on the RF attenuator element that changes the amplitude of the RF signal passing through it. As the dc voltage increases, the RF output signal attenuates, while the RF input signal remains constant. The dc voltage can be adjusted to provide a desired amount of attenuation.

The ATT-0444-02-HEX-02 is a powerful and cost-effective solution for adjusting RF signal levels in various wireless applications. It provides high performance and linearity over its operating range and is a reliable and stable solution for reducing signal levels while preserving signal fidelity and waveform. This attenuator is available in a variety of packages and provides unmatched flexibility in creating custom attenuation solutions.
