94 GHz BGA Socket Design

Ironwood Electronics has recently introduced a new BGA socket design using high performance elastomer capable of 94GHz, very low inductance and wide temperature applications. The GT-BGA-2152 socket is designed for 17x17 mm package size and operates at bandwidths up to 94GHz with less than 1dB of insertion loss. The socket is designed with center opening for air flow. The contact resistance is typically 30 milliohms per pin. The socket is mounted on the target PCB with no soldering, and uses very small real estate allowing capacitors/resistors to be placed close by. Other passive components can be placed on the back side of PCB by creating custom cutouts in the stiffener plate.

Microwave Assemblies

Times Microwave Systems announced its new InstaBend™ high performance microwave assemblies. InstaBend microwave assemblies provide a flexible preassembled design for interconnects between RF circuit cards, modules and enclosure panels. InstaBend is ideal for in-the-box applications with space constraints including space flight, thermal vacuum, microwave test, and many other commercial and military applications. The cable can be bent very closely behind the connector, minimizing footprint, saving space and simplifying cable routing. This also eliminates the need to protect the back of the connector.

Qorvo® to Create State-of-the-Art Semiconductor Packaging Center

Qorvo® has been selected by the U.S. government to create a State-of-the-Art (SOTA) Heterogeneous Integrated Packaging (SHIP) RF production and prototyping center. The SHIP program will ensure that microelectronics packaging expertise and leadership is available for both U.S. defense contractors and commercial clients that require design, validation, assembly, test and manufacturing of next-generation RF components.

The exclusive SHIP Other Transaction Agreement (OTA), worth up to $75 million, was awarded to Qorvo by the Naval Surface Warfare Center (NSWC), Crane Division. This program is funded by the Office of the Undersecretary of Defense for Research and Engineering’s (OUSD R&E) Trusted and Assured Microelectronics Program (T&AM), and is administered by the Strategic & Spectrum Missions Advanced Resilient Trusted System (S²MARTS) Other Transaction Agreement (OTA), managed by National Security Technology Accelerator (NSTXL).

Under the SHIP program, Qorvo will design and deliver the highest levels of heterogeneous packaging integration. This is essential to meet the size, weight, power and cost (SWAP-C) requirements for next-generation phased array radar systems, unmanned vehicles, electronic warfare platforms and satellite communications.
