Abstract
Methods and devices for processing of RF signals according to different gain modes are presented. According to one aspect, an active amplification mode is provided by switchable active paths coupled to respective input RF signals and a passive attenuation mode is provided by switchable passive paths coupled to the respective RF signals. According to another aspect, a common switchable feedback path coupled to the switchable active paths is used to provide an active attenuation mode. Coupling of the common switchable feedback path to the switchable active path is provided by switches of the switchable passive paths, including for coupling both ends of the common switchable feedback path or just one end.
