Abstract
An electronically reconfigurable matching network having a plurality of electronically reconfigurable components is disclosed. Each of the plurality of electronically reconfigurable elements includes a plurality of selectable impedance elements coupled together. Each selectable impedance element includes an impedance element coupled between first and second end terminals and a field-effect transistor (FET)-based switch coupled between the first and second end terminals. The FET-based switch includes a first FET having first and second current terminals coupled to a first gate terminal and a second FET having a third current terminal coupled to the first gate terminal, a fourth current terminal, and a second gate terminal coupled to a first control terminal; and a third FET having a fifth current terminal coupled to the first end terminal, a sixth current terminal coupled to the second end terminal, and a third gate terminal coupled to the third current terminal.
