Claim Text:
1. A digital step attenuator (DSA) cell comprising: (a) an input port; (b) an output port; (c) a first control input port; (d) a first resistive element having a first terminal and a second terminal; (e) a first switch element having an input terminal, an output terminal and a control terminal, the input terminal being coupled to the input port and the output terminal being coupled to the output port and the control terminal being coupled to the first control input port; (f) a first inductive coupling having an inductance, the first inductive coupling electrically connecting the input terminal of the first switch element to the first terminal of the first resistive element, and (g) a second inductive coupling having an inductance, the second inductive coupling electrically connecting the output terminal of the first switch element to the second terminal of the first resistive element;
