Abstract
Systems, devices and methods related to radio-frequency (RF) step attenuators. In some embodiments, a step attenuator can include an attenuator circuit having stages connected in series between a first node and a second node. The stages can include a plurality of first attenuation steps with each configured to provide switchable attenuation with a first gain. The stages can further include a plurality of second attenuation steps with each configured to provide switchable attenuation with a second gain. The step attenuator can further include a controller in communication with the attenuator circuit. The controller can be configured to control the switchable attenuation of each of the first attenuation steps and the second attenuation steps.
