Publication number: 20230283311Abstract: A wireless communication device includes an antenna array with multiple antenna elements, an array of power amplifiers, and an array of phase shifters. Each antenna element is coupled to a power amplifier and a phase shifter. The device also includes transmitter circuitry coupled to the antenna array to encode a constant amplitude signal, which includes a power amplifier enable code to indicate which power amplifiers are to run in a subsequent data sample and a beam direction code to control beam direction of each phase shifter of the array of phase shifters in the subsequent data sample. The constant amplitude signal is then provided to the array of antenna elements and amplitude and phase modulation is combined over an air interface into a composite modulated signal.Type: ApplicationFiled: December 23, 2021Publication date: September 7, 2023Inventors: Benjamin Jann, Ashoke Ravi, Paolo Madoglio

Patent number: 9438265Abstract: Representative implementations of devices and techniques provide a phase multiplexer that may be associated with at least a communication device. The described phase multiplexer may be able to switch between input phases without distorting a pulse width of a given input phase. In one implementation, this is achieved by enabling one phase at a time. More specifically, a gating window specific for each given phase is provided. The gating window is designed to avoid glitches associated with signals at an output of the phase multiplexer. Furthermore, the gating window is designed to avoid the generation of pulse width modifications.Type: GrantFiled: January 14, 2014Date of Patent: September 6, 2016Assignee: Intel CorporationInventors: Paolo Madoglio, Stefano Pellerano
