Abstract: Methods and devices for radio frequency (RF) loopback for transceivers are described. A transceiver for communicating RF signals with a target device may transmit signals at a transmit frequency and receive signals at a (different) receive frequency. The transceiver may include a waveguide diplexer for separating and combining signals based on frequency. The transceiver may be configured to couple a loopback signal from a common port of the waveguide diplexer; the loopback signal may be based on a transmit signal. The transceiver may include a loopback translator to translate the loopback signal from the transmit frequency to the receive frequency and provide the translated loopback signal to a receiver used for receiving signals from the target device. The receiver may compare the translated loopback signal with a representation of the transmit signal to generate a compensation signal. A transmitter may use the compensation signal to adjust subsequent transmit signals.

Abstract: Disclosed is an antenna apparatus including an antenna substrate having a first surface and a second surface on opposite 2024/054268 sides. Antenna elements are formed on the first surface, and vias are formed within the antenna substrate. The antenna apparatus further includes a beamforming network (BFN) including a plurality of semiconductor components, each having a third surface facing the antenna substrate; and metal pillars attaching the second surface to the third surface to thereby attach the semiconductor components to the antenna substrate. The semiconductor components are RF coupled to the antenna elements through the vias. Molding material is formed on the second surface and at least partially encapsulates each of the semiconductor components.

Abstract: The present disclosure, for example, relates to one or more techniques for linearizing a signal in a communications system. An input signal may be obtained at a beginning of a signal path of a radio frequency (RF) communication device. The RF communication device may estimate subsequent distortion of the input signal due to the signal path. The estimated distortion may include estimated phase distortion and estimated amplitude distortion of the input signal. The RF communication device may adjust phase and amplitude within the signal path to compensate for the estimated phase distortion and the estimated amplitude distortion to produce an adjusted signal. The phase within the signal path of the input signal may be adjusted separately from the amplitude within the signal path of the input signal. The RF communication device may generate a linearized signal at an end of the signal path based at least in part on the adjusted signal.
