Patent number: 11489255Abstract: A phase shifter that includes an RF splitter is disclosed. The RF splitter is arranged so that an RF input signal is provided to, and split over portions of, a feed line that connects an antenna element with a radio transmitter/receiver/transceiver, thus realizing a feed line splitter. Feed line splitters described herein are provided with switches that allow changing a point at which the RF input signal is fed to the feed line, where the switches may be semiconductor-based or MEMS-based switches. The point at which the RF input signal is provided to the feed line to be split defines the electrical path length that the RF energy will travel down each respective path of the feed line splitter, which, in turn, changes the phase shift realized at each output of the feed line splitter. Different antenna elements may be coupled to different outputs of the feed line splitter.Type: GrantFiled: May 8, 2020Date of Patent: November 1, 2022Assignee: ANALOG DEVICES INTERNATIONAL UNLIMITED COMPANYInventors: Padraig Fitzgerald, Yong Zhang, Padraig McDaid, Dragoslav Culum, Philip Brennan, Derek Nolan

Patent number: 10725959Abstract: SPI Round Robin Mode for Single-Cycle MUX Channel Sequencing. SPI round robin mode is an SPI mode applicable for MUX devices control. It allows the MUX output to connect to the next input channel sequentially in just one clock cycle. Configurations can be made such as: clock edge to use (rising/falling), ascending/descending channel sequence, and enabling/disabling the channels to go through. The device supersedes an ADC with built in sequencing and is applicable to multiplexing, switching, instrumentation, process control and isolation application—while retaining SPI device control and operation.Type: GrantFiled: March 11, 2019Date of Patent: July 28, 2020Assignee: Analog Devices Global Unlimited Company, Inc.Inventors: David Aherne, Jofrey Santillan, Wes Vernon Lofamia, Paul O'Sullivan, Padraig McDaid

Patent number: 9324478Abstract: A high speed cable with terminating assemblies at the respective ends of the cable includes a ground wire, one or more signal wires, and a conductive layer enclosing the ground wire and the signal wires. The ground wire as well as the signal wires and the conductive layer extend into the terminating assemblies, in each of which corresponding inductive elements are coupled between the conductive layer and the ground wire. In each terminating assembly, the ground wire is shunted to the conductive layer by inductive elements, thus providing added low frequency connectivity in the cable, while at the same time blocking high frequency noise energy that may be present in the ground wire and preventing it from being coupled into, and transmitted through, the conductive layer.Type: GrantFiled: August 29, 2013Date of Patent: April 26, 2016Inventors: John Martin Horan, David McGowan, Padraig McDaid
