Electronic Devices with Power Boosting for High Frequency Communication: abstract simplified (18184555)

• This abstract for appeared for patent application number 18184555 Titled 'Electronic Devices with Power Boosting for High Frequency Communication'

Simplified Explanation

This abstract describes an electronic device that includes wireless circuitry with light sources, photodiodes, a resonating element, and a common gate amplifier (CGA). In transmit mode, the photodiodes use optical local oscillators to generate equal portions of an antenna current, which is then amplified by the CGA for transmission through the resonating element. In receive mode, the resonating element generates an antenna current that is amplified by the amplifier and sent to the photodiodes. By using multiple photodiodes connected to the amplifier in a current sharing configuration, the power can be boosted. The amplifier has a wide bandwidth, performs impedance matching between the resonating element and the photodiodes, and isolates the photodiodes from antenna mismatch. The antenna can be integrated into a phased antenna array to further increase power.

Original Abstract Submitted

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.
