Patent number: 11658390Abstract: Antenna package structures are provided to implement wireless communications packages. For example, an antenna package includes multilayer package substrate, a planar antenna array, antenna feed lines, and resistive transmission lines. The planar antenna array includes an array of active antenna elements and dummy antenna elements surrounding the array of active antenna elements. Each active antenna element is coupled to a corresponding one of the antenna feed lines, and each dummy antenna element is coupled to a corresponding one of the resistive transmission lines. Each resistive transmission line extends through the multilayer package substrate and is terminated in a same metallization layer of the multilayer package substrate.Type: GrantFiled: January 23, 2020Date of Patent: May 23, 2023Assignees: International Business Machines Corporation, Ericsson ABInventors: Christian W. Baks, Daniel J. Friedman, Xiaoxiong Gu, Duixian Liu, Alberto Valdes Garcia, Joakim Hallin, Ola Ragnar Tageman

Patent number: 11126215Abstract: A clock signal polarity controlling circuit comprises a first latch comprising a clock input, a data input and an output. The data input is coupled to an output of a clock signal generator, the clock input is coupled to a reference clock signal. The clock signal polarity controlling circuit further comprises a second latch comprising a clock input, a data input and an output. The data input is coupled to the output of the first latch, the clock input is coupled to the reference clock signal. The circuit further comprises an XOR circuit comprising a first and second inputs and an output. The first and second inputs are coupled to the output of the second latch and the output of the clock signal generator respectively, and a clock signal having a polarity controlled by the reference clock signal is generated at the output of the XOR circuit.Type: GrantFiled: December 18, 2017Date of Patent: September 21, 2021Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Joakim Hallin, Olov Haapalahti

Publication number: 20210242947Abstract: A mixer circuitry comprises a mixer, a local oscillator (LO) leakage detector, a digital LO leakage cancellation controller and a DAC arrangement. The mixer is configured to mix a first LO signal having an LO frequency fLO with an intermediate frequency (IF) signal and generate an output signal, i.e. a wanted signal. The LO leakage detector measures the LO leakage at the output of the mixer in the presence of the wanted signal. Then in the digital LO leakage cancellation controller, a digital algorithm is run that automatically adjusts the LO leakage in the mixer by steering the digital-to-analog converter arrangement such that the intermediate frequency input signal level to the mixer is adjusted.Type: ApplicationFiled: April 23, 2021Publication date: August 5, 2021Inventor: Joakim Hallin
