Patent ID: 11923901
Assignee: APPLI INC.
Field: Telecommunications (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 11:
12. An electronic device comprising:
a photodiode;
an optical signal path configured to illuminate the photodiode using a first optical local oscillator (LO) signal and a second optical LO signal that is offset in wavelength with respect to the first optical LO signal;
an optical modulator disposed along the optical signal path;
a digital-to-analog converter (DAC) configured to output wireless data;
a transmit path that couples the DAC to the optical modulator and that is configured to convey the wireless data from the DAC to the optical modulator, the optical modulator being configured to modulate the wireless data onto the second optical LO signal;
an antenna radiating element coupled to the photodiode, wherein the photodiode is configured to generate, based on the first optical LO signal, the second optical LO signal, and a bias voltage applied to the photodiode, a current at a frequency greater than or equal to 100 GHz on the antenna radiating element, the current on the antenna radiating element being configured to transmit wireless signals that include the wireless data;
an analog-to-digital converter (ADC); and
a receive path that couples the photodiode to the ADC.
