Abstract

Electronic devices may include unshielded connectors that convey radio-frequency signals with external devices. A first electronic device may include transmitter circuitry that transmits radio-frequency signals to phase shifting circuitry. The phase shifting circuitry may pass the radio-frequency signals to a first conductive contact of a connector on the first device, may generate modified signals by applying a phase shift of approximately 180 degrees to the radio-frequency signals, and may provide the modified signals to a second conductive contact on the connector. To mitigate undesirable resonance and radiation at the connector, the connector may concurrently convey the radio-frequency signals and the modified signals to an external device over the first and second contacts while mating contacts on a connector of the external electronic device are in electrical contact with the first and second conductive contacts.
