Classification: CPC H  G | IPC G  H

Claim 15:
16. An electronic device comprising:
an optical signal generator configured to generate an optical local oscillator (LO) signal and a set of optical tones that are evenly spaced in frequency and that are offset in frequency from the optical LO signal, the set of optical tones having at least a first optical tone and a second optical tone;
a first photodiode coupled to a first antenna radiating element;
a second photodiode coupled to a second antenna radiating element; and
an optical splitter coupled to the optical signal generator through a first optical path, coupled to the first photodiode over a second optical path, and coupled to the second photodiode over a third optical path, the optical splitter being configured to transmit the optical LO signal and the first optical tone to the first photodiode and being configured to transmit the optical LO signal and the second optical tone to the second photodiode, the first photodiode and the first antenna radiating element being configured to convey first wireless signals at a first frequency greater using the optical LO signal and the first optical tone, and the second photodiode and the second antenna radiating element being configured to convey second wireless signals at a second frequency that is different from the first frequency using the optical LO signal and the second optical tone.
