Publication number: 20240145912Abstract: Methods and devices provide a test signal to each of a plurality of antenna channels via a test signal line. Each antenna channel includes an amplitude adjustor and a phase adjustor associated with at least one antenna element. For each antenna channel, the test signal provided to the antenna channels is modulated to produce a modulated test signal. The modulated test signal is produced by: i) controlling the amplitude adjustor of the antenna channel to vary a current amplitude of the test signal between a plurality of amplitude states, and ii) controlling the phase adjustor of the antenna channel to vary a current phase of the test signal between a plurality of phase states. A received test signal received from the antenna channels is processed to determine amplitude and phase errors associated with the modulated test signals associated with the antenna channels.Type: ApplicationFiled: February 8, 2022Publication date: May 2, 2024Inventors: Avigdor BRILLANT, David PEZO, David CAHANA, Rafael AZOULAY

Patent number: 8660208Abstract: Apparatus and methods for QAM modulation are disclosed using dual polar modulation. QAM modulation of a signal is accomplished by translating a QAM signal into two phasors having the same or constant amplitude and then phase shifting one of the phasor by 180 degrees for a differential load. The phasors are then polar modulated such that, when differentially combined in the load through summation or superposition, a QAM modulated symbol results. The use of constant amplitude phasors when power amplified for transmission of QAM modulated signals allows amplifiers to be operated in a saturation mode with greater efficiency than conventional amplifiers used in QAM modulation, which operate in a less efficient linear mode to effect amplitude modulation. Additionally, differential combining of the phasors affords relaxation of the turns of a transformer used in amplifying the phasors.Type: GrantFiled: October 19, 2010Date of Patent: February 25, 2014Assignee: QUALCOMM IncorporatedInventors: Avigdor Brillant, David Pezo, Haim M.

Publication number: 20120243447Abstract: Certain aspects of the present disclosure provide a dual antenna distributed radio frequency front end (RFFE). RFFE topologies described herein may provide lower insertion loss (IL), reduced emission mask, decreased power consumption, and/or lower noise figure (NF) compared to conventional RFFE topologies. One example apparatus for wireless communications generally includes first and second power amplifiers (PAs) for amplifying signals for transmission, a transmit antenna for transmitting the amplified signals, a receive antenna for receiving other signals to be processed in a receive path, and a first transmit filter configured to filter the amplified signals from the first PA before amplification by the second PA. For certain aspects, a divided inter-stage filter providing overlapping frequency bands may be utilized. For certain aspects, the RFFE may support frequency-division duplexing (FDD)/TDD (time-division duplexing) coexistence, including support for FDD/TDD MIMO (multiple input multiple output).Type: ApplicationFiled: March 19, 2012Publication date: September 27, 2012Applicant: QUAL COMM IncorporatedInventors: Haim M.
