Millimeter wave (mmWave) technology, apparatuses, and methods that relate to transceivers, receivers, and antenna structures for wireless communications are described. The various aspects include co-located millimeter wave (mmWave) and near-field communication (NFC) antennas, scalable phased array radio transceiver architecture (SPARTA), phased array distributed communication system with MIMO support and phase noise synchronization over a single coax cable, communicating RF signals over cable (RFoC) in a distributed phased array communication system, clock noise leakage reduction, IF-to-RF companion chip for backwards and forwards compatibility and modularity, on-package matching networks, 5G scalable receiver (Rx) architecture, among others.

Wireless communication technology, apparatuses, and methods

In a communication device and corresponding methods, a hierarchical, reduced power, beam search process includes a hierarchical activation of the radio frequency frontend (RFFE), transceiver, and baseband integrated circuit (BBIC) for a beam searching operations. For example, a first signal metric measurements can be performed to determine signal information. An operating mode can be determined based on the signal information. In a first operating mode, one or more second signal metric measurements can be performed for a subset of beamforming configurations of the wireless communication device to determine beamforming information. In a second operating mode, one or more third signal metric measurements can be performed on the beamforming configurations to determine the beamforming information.

Communication scanning method and system

Techniques are provided for reducing or mitigating phase noise of a digital phase lock loop or the system depending on the digital phase lock loop. In an example, a multiple-mode digital phase lock loop can include a digital phase lock loop (DPLL), multiple frequency scalers configured to receive a reference clock, and a multiplexer configured to receive a mode command signal and to couple an output of one of the multiple frequency scalers to an input of the DPLL in response to a state of the mode command signal.

Techniques for addressing phase noise and phase lock loop performance

Techniques to fabricate an RF filter using 3 dimensional island integration are described. A donor wafer assembly may have a substrate with a first and second side. A first side of a resonator layer, which may include a plurality of resonator circuits, may be coupled to the first side of the substrate. A weak adhesive layer may be coupled to the second side of the resonator layer, followed by a low-temperature oxide layer and a carrier wafer. A cavity in the first side of the resonator layer may expose an electrode of the first resonator circuit. An RF assembly may have an RF wafer having a first and a second side, where the first side may have an oxide mesa coupled to an oxide layer. A first resonator circuit may be then coupled to the oxide mesa of the first side of the RF wafer.

Techniques for integrating three-dimensional islands for radio frequency (RF) circuits

Embodiments of front-end module (FEM) circuitry and a communication device are generally described herein. In some embodiments, the FEM circuitry may be configured to provide uplink (UL) multiple-input multiple-output (MIMO) signals and/or UL carrier aggregation (CA) signals for transmission by the communication device. The FEM circuitry may comprise a hybrid coupler to generate a first antenna transmit signal and a second antenna transmit signal. The FEM circuitry may further comprise one or more tunable phase shifters. In some embodiments, the phase shifters may phase-shift a first radio frequency (RF) signal and a second RF signal according to a 90 degree phase difference to generate the hybrid coupler input signals. Accordingly, the antenna transmit signals may be transmitted according to the UL-MIMO configuration.

Apparatus for uplink multi-antenna communication based on a hybrid coupler and a tunable phase shifter

An apparatus for interference cancellation in wireless communication systems configured for reception, comprises a receive signal path configured to convey an overall receive (Rx) signal comprising an Rx signal and a residual transmit (Tx) signal, from an antenna port to an Rx input port of a transceiver, and at least one cancellation path configured to receive a leakage Tx signal from the antenna port. Further, the apparatus comprises a cancellation unit configured to apply a cancellation signal to the overall Rx signal in the receive signal path and a compensation unit configured to generate the cancellation signal by modifying the leakage Tx signal in the cancellation path, based on a compensation control signal. In addition, the apparatus comprises a feedback receiver unit configured to generate the compensation control signal based on the residual Tx signal in the overall Rx signal and the cancellation signal.

Architecture and control of analog self-interference cancellation

An apparatus for interference cancellation in a wireless communication system, includes a cancellation unit configured to receive a transmit (Tx) signal from an output port of a power amplifier and a receive (Rx) signal from an antenna, and generate a cancellation of a primary portion of the Tx signal from the Rx signal at an output thereof, leaving a residual portion as a residual Tx signal, wherein the output of the cancellation unit is coupled to an Rx input port of a transceiver. The apparatus further includes a compensation control unit configured to modify one or more signals within the cancellation unit, based on the residual Tx signal at the output of the cancellation unit.

Architecture and control of hybrid coupler based analog self-interference cancellation

A doubly balanced transceiver system having a transmit terminal (TX), a receive terminal (RX), and an an antenna terminal (ANTENNA), 180&#xb0; hybrids (), 90&#xb0; hybrids (and), a power amplifier () and a RX/TX switch () for disabling the power amplifier so that signals received at the transmitter are reflected to the receive terminal (RX). The 180&#xb0; hybrids () preferably split and re-combine signals into parallel paths. A loopback test mode is preferably provided by use of an antenna isolation switch () to enable a power detect terminal (POWER_DETECT). This eliminates pricey and problematic GaAs switches, and allows the use of low cost silicon for the power amplifier. The doubly balance architecture also has the advantage of eliminating common-mode noise, and reflection problems with the PA gain stages. Additionally, greater power can be extracted from the power amplifier. Further the arrangement has less insertion loss compared to a GaAs switch. Also, dependant upon system specifications, it may be possible to eliminate harmonic filtering at the power amplifier output.
