Abstract

In accordance with an embodiment, a circuit includes a plurality of switching networks coupled between a corresponding plurality of RF ports and a common RF port, and a control circuit. Each of the plurality of switching networks includes a first switch coupled between its corresponding RF port and the common RF port, and at least one of the plurality of switching networks includes a selectable network coupled between the first switch and the common RF port, such that the selectable network provides a DC path in a first state and a series capacitance in a second state.
