A phase shifter-attenuator system having: a controller for producing a digital word representative of a predetermined phase shift and attenuation provided to an input signal; and a phase shifter-attenuation section. The phase shifter-attenuation section includes: a phase rotator for providing one of a plurality combinations of phase shifts-attenuation states to the input signal selectively in accordance with one portion of the produced digital word; and an attenuation section for distributing the plurality of combinations of phase shift-attenuation states over a selected range of attenuations, such range being selected in accordance with a second portion of the produced digital word. The phase shifter-attenuator section provides one of a plurality of combinations of phase shift-attenuation states to the input signal selectively in accordance with one portion of the produced digital word, the combinations being distributed over a range of attentions selected in accordance with a second portion of the digital word.
