Abstract
An electronic device may be provided with wireless circuitry that includes one or more antennas and a transceiver. An integrated circuit may be coupled between the transceiver and the antenna and may include multiple tunable components such that tune the response of the antenna. The control signals may be generated by a tuning controller external to the integrated circuit. Shared control interface circuitry may be formed on the integrated circuit for interfacing between the tuning controller and each of the tunable components on the integrated circuit. The control interface circuitry may include a conductive path and decoupling circuitry that routes the control signals to corresponding control inputs on each of the tunable components. Sharing the control interface circuitry between each tunable component on the integrated circuit may minimize the space required on the integrated circuit for controlling the response of the antenna.
