Attenuators for electronic applications

Abstract:

In some embodiments, an attenuator for electronic application can include a first group of attenuation steps, with each configured to switchably provide a first fixed attenuation value. The attenuator can further include a second group of attenuation steps, with each configured to switchably provide a second fixed attenuation value. Magnitude of the second fixed attenuation value can be less than magnitude of the first fixed attenuation value. The attenuator can be configured to be capable of providing a total attenuation value from approximately zero to a sum of the attenuation steps of the first group and the second group in increments of the second fixed attenuation value.
