Patent number: 11973522Abstract: Aspects of this disclosure relate to a front end architecture for selectively adding an external carrier aggregation band. A switch element can connect a radio frequency signal path to an antenna path through a frequency domain multiplexer, such as a diplexer, in a first mode. The switch element can connect the radio frequency path to the antenna path and bypass the frequency domain multiplexer in a second mode. The frequency domain multiplexer can be external to a front end module that include the radio frequency signal path. In the first mode, a front end system can support carrier aggregation with a band associated with circuitry implemented external to the front end module.Type: GrantFiled: March 10, 2021Date of Patent: April 30, 2024Assignee: Skyworks Solutions, Inc.Inventors: Jen-Chien Chang, Reza Kasnavi, Roman Zbigniew Arkiszewski, Jeffrey Gordon Strahler, John G.

Patent number: 11870643Abstract: A reconfigurable triplexer that can support more frequency bands than a traditional triplexer is disclosed. For example, the reconfigurable triplexer can handle frequencies of several hundred megahertz up to 10 gigahertz. Further, certain implementations of the reconfigurable multiplexer can reduce or eliminate frequency dead zones that exist with traditional multiplexers. The reconfigurable triplexer includes a multi-stage filter bank capable of supporting a number of frequency bands and a bypass circuit that enables the triplexer to support a variety of sets of frequencies. For instance, unlike traditional triplexers, the reconfigurable triplexer can support both frequency bands with relatively narrow spacing and frequency bands with relatively wide spacing. Further, the inclusion of the bypass circuit enables the reduction or elimination of dead zones between supported frequencies.Type: GrantFiled: June 30, 2021Date of Patent: January 9, 2024Assignee: Skyworks Solutions, Inc.Inventors: Yang Hou, Reza Kasnavi, Jianxing Ni, Shanshan Zhao

Patent number: 11764734Abstract: The disclosure relates to a signal combiner for a Doherty power amplifier architecture, the signal combiner including a termination circuit on an isolation port, the termination circuit being tuned to improve performance of the Doherty power amplifier. The architecture includes a carrier amplifier and a peaking amplifier. The peaking amplifier modulates the load seen by the carrier amplifier, allowing the carrier amplifier to remain in high-efficiency, saturated operation even at back-off. This load modulation can be achieved using impedance matching networks having an impedance matched to a specific frequency. The architectures include tuned or tailored signal combiners with termination circuits on isolation ports. The termination circuits are tuned or tailored for particular operating frequencies to enhance operation.Type: GrantFiled: August 24, 2021Date of Patent: September 19, 2023Assignee: SKYWORKS SOLUTIONS, INC.Inventors: Kunal Datta, Reza Kasnavi, Aleksey A.

Patent number: 11101775Abstract: The disclosure relates to a wideband, tunable hybrid-based combiner for a Doherty power amplifier architecture. The architecture includes two parallel power amplifiers: a carrier amplifier and a peaking amplifier. The peaking amplifier modulates the load seen by the carrier amplifier, allowing the carrier amplifier to remain in high-efficiency, saturated operation even at back-off. This load modulation can be achieved using impedance matching networks having an impedance matched to a specific frequency. Typically, a multi-mode/multi-band power amplifier module that does not include a tunable impedance circuit as disclosed herein, several Doherty power amplifier modules (each of which uses two amplifiers) would be used to cover several bands, which may make implementation costly and/or impractical. Thus, the architectures described herein provide wideband amplification using a Doherty amplifier configuration.Type: GrantFiled: July 16, 2019Date of Patent: August 24, 2021Assignee: SKYWORKS SOLUTIONS, INC.Inventors: Kunal Datta, Reza Kasnavi, Aleksey A.
