Coaxial Fixed Attenuator

Coaxial attenuator is a device used to reduce the signal power in a coaxial transmission line. It is commonly used in electronic and communication systems to control signal strength, prevent signal distortion, and protect sensitive components from excessive power.

Coaxial attenuators are generally composed of connectors (usually using SMA, N, 4.30-10, DIN, etc.), attenuation chips or chipsets (can be divided into flange type: usually selected for use in lower frequency bands, rotary type can achieve higher frequencies) Heat sink (Due to the use of different power attenuation chipsets, the heat emitted cannot be dissipated by itself, so we need to add a larger heat dissipation area to the chipset. Using better heat dissipation materials can make the attenuator work more stably.)

Overview

The attenuation value of a coaxial attenuator is usually expressed in decibels (dB) and indicates the amount of signal power reduced.
The attenuator can be fixed (with a constant attenuation value) or adjustable (allowing adjustment of the attenuation level).
Attenuators are used to simulate actual signal conditions during testing and measurement.
Place the attenuator between the amplifier and the load to 
prevent over-driving the downstream components.
Attenuators are used to compensate for signal imbalances and improve the overall signal quality of the communication system. Attenuators regulate
signal strength to meet specific requirements such as wireless communications, radio and television systems.
When selecting a coaxial attenuator, factors such as frequency range, power handling capability, impedance matching,
and connector type should be considered to ensure correct signal attenuation and system compatibility.
Our company has many years of experience in the research and development, production, and sales of coaxial attenuators.
The coaxial attenuators we produce and sell can reach a maximum frequency of 110G, with stable and excellent performance.
Welcome customers to choose, you can also contact sales personnel to customize according to your specific needs.
