Attenuators

Attenuators are electronic devices used to reduce the level of a signal without distorting the waveform. They are typically used to reduce the signal strength of a signal that is too powerful to be monitored correctly without distortion. Attenuators are usually categorized based on the type of attenuation: voltage, current, impedance, power etc. One example of an attenuator is the ATT-0389-10-NNN-02.

Application Field

The ATT-0389-10-NNN-02 attenuator is designed for use in the emerging Wireless Communications of the future. It is suitable for use in applications such as cellular base stations, microwave point-to-point links, and high power transmitters. This attenuator can attenuate signals up to 30 dB with a minimum power dissipation of 0.2 watts, and can operate up to a maximum frequency of 5.4 GHz.

Working Principle

The new ATT-0389-10-NNN-02 attenuator is based on a constant-impedance architecture, utilizing thin-film surface-mount resistors. Its resistors are electronically adjustable, allowing for precise signal strength control. The attenuator can be used in an amplifier or connected directly to the input or output of a component to control signal strength. The attenuator consists of two resistors in series, each one having a different resistance and each one connected through a resistive element to ground. A combination of resistors is then connected in parallel to an external signal, a DC source and an output. The resistive elements allow for precise signal control, offering a maximum signal to noise ratio of 85 dB. In addition, the attenuator offers excellent RF characteristics such as low insertion loss, high return loss, and low distortion.

The ATT-0389-10-NNN-02 attenuator has a low profile, making it ideal for easy integration into existing systems. The attenuator is also designed for long life and reliability with mean time between failure (MTBF) rated at 230,000 hours. It is capable of sustaining up to 10 dB of power variation, allowing for use in a variety of applications and applications on the go.

The ATT-0389-10-NNN-02 attenuator offers a wide range of applications and is an ideal solution for attenuating signals, whether for transmitting or receiving, in any communication system. Its small size, low profile, high performance, and excellent RF characteristics make it an ideal choice for use in RF systems, such as cellular base stations, microwave point-to-point links, and high-powered transmitters.
