Abstract
An electronic device may include radio-frequency transceiver circuitry and antenna structures. The radio-frequency transceiver circuitry may transmit signals for the antenna structures that pass through electrical components such as switches. Harmonics of the transmitted signals may be generated as the signals pass through the electrical components. To reduce interference that might otherwise adversely affect sensitive receiver circuitry in the electronic device, adjustable filter circuitry may be interposed between the electrical components and the antenna structures. Control signals may adjust the adjustable circuitry in real time during operation of an electronic device to ensure that transmitted signals can pass through the adjustable filter circuitry while blocking the harmonic signals.
