Original Abstract Submitted

an electronic device may include wireless circuitry with a non-coherent receiver and a phased antenna array that receives a radio-frequency signal having a sub-thz carrier and one or two sidebands separated from the carrier by an intermediate frequency and carrying wireless data. the receiver may include respective receive paths coupled to each antenna in the phased antenna array, a signal combiner coupled to each of the receive paths, and a demodulator. each receive path may have a respective passive square law envelope detector and a respective phase shifter. the envelope detectors may generate intermediate frequency signals at the intermediate frequency based on the radio-frequency signals. the phase shifters may phase shift the intermediate frequency signals to generate a phase-aligned intermediate frequency signal. the demodulator may recover the wireless data by demodulating the phase-aligned intermediate frequency signal.
