a cellular telephone, a tablet, a wearable electronic device, or a notebook computer;

processing circuitry disposed within the portable electronic device and configured to generate first radio data signals and second radio data signals;

a first radiohead disposed within the portable electronic device and configured to generate first radio frequency (RF) signals at a first radio frequency based at least in part on the first radio data signals;

a second radiohead disposed within the portable electronic device and configured to generate second RF signals at a second radio frequency based at least in part on the second radio data signals;

a first optical path coupled between the first radiohead and the processing circuitry configured to communicate the first radio data signals from the processing circuitry to the first radiohead; and

a second optical path coupled between the second radiohead and the processing circuitry and configured to communicate the second radio data signals from the processing circuitry to the second radiohead.
