Attenuator principle
Attenuator is a circuit used to introduce a predetermined attenuation within a specified frequency range. It is generally indicated by the decibel of the attenuation introduced and the ohm of its characteristic impedance. Attenuators are widely used in CATV systems to meet the level requirements of multi ports. Such as the control of the input and output level of the amplifier and the control of the branch attenuation. There are two kinds of attenuators: passive attenuator and active attenuator. The active attenuator cooperates with other thermal elements to form a variable attenuator, which is used in the automatic gain or slope control circuit in the amplifier. Passive attenuators include Fixed Attenuators and adjustable attenuators.
Product application
• Adjust the size of the signal in the circuit;
• In the comparison method measuring circuit, it can be used to directly read the attenuation value of the measured network;
• Improve impedance matching. If some circuits require a relatively stable load impedance, an attenuator can be inserted between this circuit and the actual load impedance to buffer the change of impedance.
