Abstract: Systems and methods described herein may enable an electronic device to communicate using both a first communication system based on a first frequency spectrum (e.g., New Radio (NR)/Fifth Generation (5G) network frequencies) and a second communication system based on a second frequency spectrum (e.g., sub-terahertz (sub-THz) frequencies, Sixth Generation (6G) network frequencies)). The two communication systems may share some front-end processing circuitry, which may help with reducing complexity and footprints of sub-THz communication systems.

Abstract: Systems, methods, and devices are provided for detecting the presence of an object near an electronic device. A radio frequency (RF) system of an electronic device may include a first circuit that includes one or more transmission paths for transmitting a reference signal external to the electronic device. The RF system may include a second circuit that includes one or more receiving paths for receiving a reflection signal based on the reference signal. The RF system may also include a processor that may instruct the RF system to perform a comparison between the reference signal and the reflection signal, determine whether the object is in proximity based at least in part on whether comparison results exceed a comparison threshold, and decrease power output by the RF system below the comparison threshold.

Abstract: The representative embodiments discussed in the present disclosure relate to techniques in which a transmitter may operate in an uplink multiple-input, multiple-output (MIMO) mode of operation. More specifically, in some embodiments, the transmitter may concurrently transmit a first and a second signal within the same frequency band via a first and second antenna, respectively. Further, in some embodiments, the transmitter may include circuitry and/or logic to offset nonlinear interference present in the transmitted signals as a result of antenna coupling between the first and second antenna and a nonlinear element (e.g., a power amplifier) within the transmitter.

Abstract: Systems, methods, and devices are provided for correcting compression distortion of wireless signals due to variations in operation parameters of the radio frequency system. The method may include using circuitry to generate a reference signal that is not pre-distorted by a processing block. The method may involve receiving an envelope signal representative of a signal being transmitted by a transceiver. The method may also involve determining a first peak-to-average ratio of the envelope signal and receiving a second peak-to-average ratio of the reference signal. The method may additionally involve determining a difference between the first peak-to-average ratio and the second peak-to-average ratio. The method may also include adjusting a gain of an amplifier of the transceiver based on the difference.

The control circuitry may use the provided sensor data to generate control signals for the power supply circuitry. The control signals may adjust the envelope mapping setting of the power supply circuitry.

Abstract: A radio antenna switch module for a high frequency radio transceiver enables the radio transceiver to have a small number of receivers and transmitters and a larger number of antennas, whereby each antenna has a different diversity characteristic. The diversity between antennas provide for greater communication reliability, while the small number of receivers and transmitters allows the transceiver to operate at relatively low power compared to conventional radio transceivers. The switch module also allows for two loopback modes between the transmitter and the receiver for at-speed, low-cost self-test in production.
