Abstract
An electronic device may include wireless circuitry with light sources, a set of photodiodes, a resonating element, and a common gate amplifier (CGA). In a transmit mode, the photodiodes may use optical local oscillators to generate equal portions of an antenna current amplified by the CGA for transmission by the resonating element. In a receive mode, the resonating element may generate an antenna current which is amplified by the amplifier and passed to the photodiodes. Including multiple photodiodes coupled to the amplifier in a current sharing configuration may serve to boost power. The amplifier may exhibit a wide bandwidth, may perform impedance matching between the resonating element and the photodiodes, and may isolate the photodiodes from antenna mismatch. The antenna may be integrated into a phased antenna array to further boost power.
