Abstract
Adjustable impedance tuning circuitry includes a first impedance matching terminal, a second impedance matching terminal, and a plurality of passive components adapted to match the impedance of the first impedance matching terminal and the second impedance matching terminal. The plurality of passive components includes one or more tunable components adapted to adjust the impedance of the adjustable impedance tuning circuitry to maintain an impedance match between the first impedance matching terminal and the second impedance matching terminal over a variety of operating conditions. Each of the one or more tunable components includes one or more switches adapted to selectively alter the impedance of the tunable component. The one or more switches are integrated onto a single semiconductor die in order to facilitate the performance of the adjustable impedance tuning circuitry over a wide bandwidth.
