Coaxial Fixed Attenuator

Product Description

Coaxial Fixed Attenuator is an energy lossy RF / microwave component, which contains resistive materials. In addition to the commonly used resistive Fixed Attenuators, there are also electronically controlled quick adjustment attenuators. Attenuators are widely used in various occasions that require power level adjustment.

Basic Composition

The basic material that makes up a Coaxial Fixed Attenuator is a resistive material. A common resistor is a basic form of coaxial attenuator, and the resulting resistive attenuator network is a lumped parameter attenuator. Through a certain process, the resistive material is placed in the radio frequency/microwave circuit structure of different frequency bands to form an attenuator of the corresponding frequency.

Specification

The Main Purpose of Coaxial Fixed Attenuator

1. Control the power level: Control the output power of the local oscillator in the microwave superheterodyne receiver to obtain the best noise figure and frequency conversion loss, and achieve the best receiving effect. In microwave receivers, automatic gain control is implemented to improve dynamic range.

2. Decoupling element: as a decoupling element between the oscillator and the load.

3. Relative standard: as a relative standard for comparing power levels.

4. Hopping attenuator used in radar anti-jamming: it is a variable attenuator with sudden change in attenuation. Usually, no attenuation is introduced. When encountering external interference, it suddenly increases the attenuation.
