Attenuator is an electronic component that provides attenuation and is widely used in electronic equipment. The operating frequency band of the attenuator refers to the use of the attenuator within a given frequency range, so that the attenuator can reach the index value. Its main fields are: adjust the size of the signal in the circuit; directly read the attenuation value of the measured network; improve impedance matching. If some circuits require a more stable load impedance, an attenuator can be inserted between the circuit and the actual load impedance, which can buffer the impedance change.
