Patent number: 11955687Abstract: Power-combining devices, and more particularly spatial power-combining and related structural arrangements are disclosed. Such structural arrangements involve mechanical connections between center waveguide sections and input and/or output coaxial waveguide sections that provide scalable structures for different operating frequency bands, improved mechanical connections, and/or improved assembly. Exemplary structural arrangements include structures that extend through center waveguide sections and into input and/or output coaxial waveguide sections, integrated mechanical structures within the center waveguide section, compression fit arrangements, dielectric inserts arranged within channels of coaxial waveguide sections, and/or various combinations thereof.Type: GrantFiled: January 10, 2022Date of Patent: April 9, 2024Assignee: Qorvo US, Inc.Inventors: Dylan Murdock, Gregory Valenti, Eric Jackson

Publication number: 20240055319Abstract: A circuit package with improved thermal management is disclosed. In one aspect, a ceramic insert is provided within a package having heat-producing circuitry thereon. The ceramic insert replaces traditional laminate inserts and provides a better thermal path to remove heat from leads and/or traces within the package. More particularly, the ceramic insert more readily transfers and/or dissipates heat that might otherwise accumulate at an output port where a solder junction may be made to couple the output port to external elements.Type: ApplicationFiled: July 6, 2023Publication date: February 15, 2024Inventors: Matthew Irvine, Dylan Murdock

Patent number: 11791251Abstract: The present disclosure relates to a package capable of handling high radio frequency (RF) power, which includes a carrier, a ring structure attached to a top surface of the carrier, an RF die attached to the top surface of the carrier within an opening of the ring structure and electrically connected to the ring structure, a heat spreader attached to a top surface of the ring structure, and an output signal lead configured to send out RF output signals generated by the RF die. Herein, the heat spreader covers a portion of the top surface of the ring structure at an output side of the package, and the output signal lead is attached to a top surface of the heat spreader. As such, the RF output signals are capable of being transmitted from the RF die to the output signal lead through the ring structure and the heat spreader.Type: GrantFiled: July 29, 2021Date of Patent: October 17, 2023Assignee: Qorvo US, Inc.Inventor: Dylan Murdock

Patent number: 11665867Abstract: Thermal structures and, more particularly, improved thermal structures for heat transfer devices and spatial power-combining devices are disclosed. A spatial power-combining device may include a plurality of amplifier assemblies and each amplifier assembly includes a body structure that supports an input antenna structure, an amplifier, and an output antenna structure. One or more heat sinks may be partially or completely embedded within a body structure of such amplifier assemblies to provide effective heat dissipation paths away from amplifiers. Heat sinks may include single-phase or two-phase materials and may include pre-fabricated complex thermal structures. Embedded heat sinks may be provided by progressively forming unitary body structures around heat sinks by additive manufacturing techniques.Type: GrantFiled: May 18, 2022Date of Patent: May 30, 2023Assignee: Qorvo US, Inc.Inventor: Dylan Murdock

Patent number: 11621469Abstract: Power-combining devices, and more particularly spatial power-combining devices with increased output power are disclosed. Increased output power may be realized by increasing a number of transmission paths for amplification that are associated with each amplifier assembly of a spatial power-combining device. Each transmission path may include an input antenna structure, an amplifier, and an output antenna structure for providing amplification of signals that pass therethrough. In this manner, a total number of transmission paths for amplification may be increased without having to increase a total number of amplifier assemblies. Further improvements to electrical separation and stability between neighboring amplifier assemblies may be provided by electrically grounded conductive sheets that are arranged between neighboring amplifier assemblies.Type: GrantFiled: April 30, 2021Date of Patent: April 4, 2023Assignee: Qorvo US, Inc.Inventors: John Kitt, Dylan Murdock

The disclosed hermetic package includes a metal base and multiple segments that are discrete from each other. Herein, a gap exists between every two adjacent ceramic wall segments and is sealed with a connecting material. The ceramic wall segments with the connecting material form a ring wall, where the gap between every two adjacent ceramic wall segments is located at a corner of the ring wall. The metal base is either surrounded by the ring wall or underneath the ring wall.Type: ApplicationFiled: August 4, 2021Publication date: February 10, 2022Inventor: Dylan Murdock
