Introduction to Attenuators

Attenuators are a class of electronic components that are used to reduce the amplitude of an electrical signal that passes through it. This reduction in signal strength or amplitude is expressed in terms of decibels (dB). These components are often used to prevent damage to sensitive equipment by curbing the strength of high power signals. Attenuators come in a variety of shapes and sizes, each with unique characteristics and capabilities.

PXV1220S-1DBN7-T Application Field and Working Principle

The PXV1220S-1DBN7-T attenuator is a broadband, high-power, non-reflective attenuator that is suitable for use in a wide range of applications, including microwave and RF amplifiers, filters, and antennas. It is a positive, non-reflective attenuator, meaning that it does not dissipate any power when the input signal is applied to it. Instead, the attenuator responds to the input signal by reducing the magnitude of the signal without adding distortion and without reflecting any power. This type of attenuator is ideal for use in systems where repeatability and accuracy of results are critical.

The PXV1220S-1DBN7-T is a broadband attenuator that can handle signal frequencies from 0.1MHz to 18GHz. It has an insertion loss of 1.2 dB and is able to deliver power up to 50 Watts. Each attenuator features a 3 dB taper to minimize thermal stress and ensure uniform signal power delivery. The PXV1220S-1DBN7-T also features a built-in PowerMatch circuit for fast and accurate settings.

The working principle of the PXV1220S-1DBN7-T is based on the use of multiple resistive networks. These networks are designed to maintain a consistent input-output impedance matching to prevent reflection from occurring. Inside the attenuator, it is designed with multiple resistor networks to account for several factors such as power loss, attenuation and impedance matching. The amount of signal attenuation is controlled by a series of switches mounted internally. When a particular configuration is applied to the attenuator, the desired amount of attenuation is peformed automatically.
