Publication number: 20240030952Abstract: Embodiments of this disclosure may include a receiver with a reconfigurable processing path for different signal conditions. Such a receiver may reconfigure between a mixer-first configuration and an amplifier-first configuration. In the mixer-first configuration, an RF input signal is not passed through an LNA for amplification before processing the RF input signal for downconversion to baseband and eventual extraction of the information in the signal. In the amplifier-first configuration, an RF input signal is passed through an LNA for amplification before processing the RF input signal for downconversion to baseband and eventual extraction of the information in the signal. Reconfiguring the receiver between mixer-first and amplifier-first configurations may be performed based on detection of jammer signals and/or measurement of signal-to-noise ratio (SNR).Type: ApplicationFiled: October 5, 2023Publication date: January 25, 2024Inventors: Jang Joon Lee, Kyle David Holland, Jian Kang, Aleksandar Miodrag Tasic, Chih-Fan Liao, Yingying Li, Lai Kan Leung, Chiewcharn Narathong

Publication number: 20230421195Abstract: Carrier aggregation (CA) may cause interference between operation on two or more carriers within a user equipment (UE). This interference can degrade signal quality on one or more of the carriers involved in the carrier aggregation, which may be referred to as “desensing” one or more carriers. One or more isolating buffers may be coupled at a down-conversion mixer at a point where the down-conversion mixer receives a signal from a transmission line for isolating the transmission line from other transmission lines. The isolating buffer may reduce the effect of interference between multiple transmission lines carrying different carriers during carrier aggregation (CA) operation. The isolating buffers may be used in an RF transceiver supporting both 5G sub-7 GHz and 5G mmWave wireless networks and carrier aggregation across sub-7 GHz and mmWave bands.Type: ApplicationFiled: June 21, 2023Publication date: December 28, 2023Inventors: Jang Joon LEE, Kyle David HOLLAND, Prakash THOPPAY EGAMBARAM, Aleksandar Miodrag TASIC

Publication number: 20230097399Abstract: Certain aspects of the present disclosure generally relate to techniques and apparatus for operating a wireless receiver of the apparatus in a high linearity mode. An example method includes operating the apparatus in a first mode with transmission of a plurality of transmit signals. The method also includes attenuating a received signal via an attenuator while operating the apparatus in the first mode. The method further includes amplifying the attenuated signal with an amplifier while operating the apparatus in the first mode. For certain aspects, the method further involves operating the apparatus in a second mode, bypassing the attenuator while operating the apparatus in the second mode, and amplifying the received signal with the amplifier while operating the apparatus in the second mode.Type: ApplicationFiled: September 24, 2021Publication date: March 30, 2023Inventors: Ahmed ABBAS MOHAMED HELMY, Francesco GATTA, Balasubramanian RAMACHANDRAN, Abhishek Ananthrao KULKARNI, Prakash THOPPAY EGAMBARAM, Hasnain LAKDAWALA, Aleksandar Miodrag TASIC, Jang Joon LEE, Kyle David HOLLAND

Publication number: 20230099161Abstract: An amplifier may include multiple stages, with the multiple stages arranged in a fan-out configuration. The fan-out configuration provides multiple amplified signals at multiple amplifier output nodes, which may be coupled to a shared set of downconverters. The shared downconverters may support processing of only a smaller bandwidth than the largest possible bandwidth of an input RF signal input to the amplifier. For example, the downconverters may support a bandwidth matching a smallest bandwidth of a supported RF signal. For example, when the amplifier is intended to support 5G mmWave RF signals and 5G sub-6 GHz RF signals, the downconverters may each individually support a bandwidth of carriers in the 5G sub-6 GHz RF signals but not individually support the entire bandwidth of a possible 5G mmWave RF signal.Type: ApplicationFiled: September 24, 2021Publication date: March 30, 2023Inventors: Kyle David Holland, Jang Joon Lee, Rahul Kodkani, Aleksandar Miodrag Tasic, Chih-Fan Liao, Lai Kan Leung, Chiewcharn Narathong

Patent number: 11569865Abstract: Wireless signal processing may be improved by using a configurable baseband filter (BBF) in the receive path of a transceiver. A configurable BBF may accommodate processing of different wireless signals in a single integrated circuit (IC) chip. For example, a single IC may support processing of 5G mmWave RF signals and 5G sub-7 GHz RF signals by reconfiguring the BBF with settings appropriate for the different wireless signals. The reconfiguring of the BBF may include adjusting a bandwidth of the BBF and/or adjusting a filter order of the BBF. The reconfiguring of the BBF may be performed in response to detection of jammer signals to improve rejection of the jammer signals.Type: GrantFiled: September 24, 2021Date of Patent: January 31, 2023Assignee: QUALCOMM IncorporatedInventors: Chih-Fan Liao, Aleksandar Miodrag Tasic, Kyle David Holland, Jang Joon Lee, Jian Kang, Lai Kan Leung, Chiewcharn Narathong
