Abstract

An electronic device (10) may include wireless circuitry (24) with light sources, a set of photodiodes (42), a resonating element (36), and a common gate amplifier, CGA (96). In a transmit mode, the photodiodes (42) may use optical local oscillators to generate equal portions of an antenna current amplified by the CGA (96) for transmission by the resonating element (36). In a receive mode, the resonating element (36) may generate an antenna current which is amplified by the amplifier (96) and passed to the photodiodes (42). 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.
