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.)
