A variable loss attenuator is provided. Two or more controllable stages each include a differential or single-ended π network. Each π network includes one or more series elements connected in series between the signal input and the signal output. Each series element includes a series transistor, which may potentially be provided without an inductor in parallel. Each π network includes a plurality of shunt elements each including at least one respective shunt transistor. An input stage connects to the first controllable stage and an output stage connects from the last controllable stage. Intermediate stages connect the controllable stages to one another. Each of the input stage, output stage, and intermediate stages include a right-handed transmission line component and coupled between the signal input and a first one of the controllable stages. Shunt inductors are located at inputs and outputs of each of the controllable stages.
