Patent attributes
An attenuator for attenuating an input signal at a predetermined rate and a step attenuation device having the same are provided. The attenuator includes first to sixth impedance components. A terminal of the first impedance component is connected to an input signal. A terminal of the second impedance component is connected to the other terminal of the first impedance component. The other terminal of the second impedance component outputs an attenuated signal. A terminal of the third impedance component is connected to a common terminal of the first and second impedance components. A terminal of the fourth impedance component is connected to a ground voltage. A terminal of the fifth impedance component is connected to the other terminal of the fourth impedance component. The other terminal of the fifth impedance component is connected to the ground voltage. A terminal of the sixth impedance component is connected to a common terminal of the fourth and fifth impedance component. The other terminal of the sixth impedance component is connected to the other terminal of the third impedance component.
