Patent number: 10887079Abstract: Digital predistortion (DPD) timing alignment in a remote unit(s) for a wireless communications system (WCS) is disclosed. In examples discussed herein, a remote unit includes a power amplifier (PA) configured to amplify a radio frequency (RF) signal before transmission. The RF signal may include an unwanted distortion term and a DPD circuit is provided in the remote unit to create an artificial distortion term to help cancel out the unwanted distortion term. The remote unit includes a DPD front-end circuit configured to generate a digital training signal corresponding to a predefined waveform pattern. The DPD circuit can be configured to perform a DPD timing alignment based on the predefined waveform pattern to determine a timing offset that is need to create the artificial distortion term. As such, it may be possible to effectively cancel the unwanted distortion term in the RF signal to improve efficiency and linearity of the PA.Type: GrantFiled: September 26, 2019Date of Patent: January 5, 2021Assignee: Corning Research & Development CorporationInventors: Nir Geron, Roi Yosy Ziv

Patent number: 10673529Abstract: Embodiments of the disclosure relate to a high-directivity directional coupler, and related methods and systems. The high-directivity directional coupler includes a first microstrip and a second microstrip disposed parallel to the first microstrip. The high-directivity directional coupler inherently generates an even mode current and an odd mode current in the second microstrip. The second microstrip provides a linear forward path for conveying the even mode current and a non-linear return path for conveying the odd mode current. The non-linear return path is longer than the linear forward path to compensate for phase velocity difference between the even mode current and the odd mode current. As a result, the odd mode current and the even mode current in the second microstrip can destructively cancel out each other, thus rendering high-directivity without compromising other performance aspects of the high-directivity directional coupler.Type: GrantFiled: May 16, 2019Date of Patent: June 2, 2020Assignee: Corning Optical Communications LLCInventor: Roi Yosy Ziv

Patent number: 10530315Abstract: Embodiments of the disclosure relate to calibrating a power amplifier. The power amplifier calibration circuit is configured to provide a plurality of bias signal combinations each including a respective first bias signal and a respective second bias signal to the power amplifier. Power amplifier performance parameters for each of the bias signal combinations can be measured and provided to a control circuit in the power amplifier calibration circuit. The control circuit is configured to rank the measured power amplifier performance parameters based on predefined ranking criteria and determines a selected bias signal combination that can optimize the power amplifier performance parameters of the power amplifier. As such, it is possible to calibrate the power amplifier to operate at a balanced performance level, thus helping to improve radio frequency (RF) coverage and performance of the remote unit in a wireless distribution system (WDS).Type: GrantFiled: April 12, 2019Date of Patent: January 7, 2020Assignee: Corning Optical Communications LLCInventors: Amit Gutman, Shlomi Kaduri, Roi Yosy Ziv

Patent number: 10530408Abstract: Embodiments of the disclosure relate to reducing out-of-channel noise in a wireless distribution system (WDS). A digital filter in a remote unit is configured to suppress out-of-channel noise in a downlink digital communications signal based on at least one filter configuration parameter received from a control circuit. The control circuit is configured to determine the filter configuration parameter based on physical characteristics of the downlink digital communications signal. By suppressing the out-of-channel noise of the downlink digital communications signal, it is possible to provide a downlink RF communications signal communicated from the remote unit that complies with a spectrum emission mask (SEM).Type: GrantFiled: February 13, 2019Date of Patent: January 7, 2020Assignee: Corning Optical Communications LLCInventors: Moshe Daniel, Roi Yosy Ziv

Publication number: 20190245601Abstract: Embodiments of the disclosure relate to antenna array beamforming in a remote unit(s) in a wireless distribution system (WDS). In this regard, a remote unit in a WDS includes an antenna array having a plurality of radio frequency (RF) antennas.
