Abstract
The invention relates to an attenuator for stepwise attenuating a radio frequency signal. The attenuator comprises a first attenuation module that is configured to stepwise attenuate a radio frequency signal within a first signal frequency range. The attenuator comprises a second attenuation module that is configured to stepwise attenuate a radio frequency signal with a second signal frequency range, wherein the second attenuation module is arranged in parallel to the first attenuation module. The attenuator further comprises a switching element, wherein the switching element switches either the first attenuation module or the second attenuation module to an output node of the attenuator.
