Broadband 1.2- and 2.4-mm Gallium Nitride (GaN) Power Amplifier Designs

The US Army Research Laboratory (ARL) has been working with Raytheon to design efficient, broadband, linear, high-power amplifiers and robust, broadband, low-noise amplifiers for future adaptive, multimodal radar systems. Raytheon has a high-performance, W-band, gallium nitride (GaN) fabrication process and a process design kit (PDK) that ARL used to design low-noise amplifiers, power amplifiers, and other circuits for future radar, communications, and sensor systems. After the first set of ARL and Raytheon designs was submitted for fabrication, test designs of broadband Class A/B power amplifiers were developed. While these designs did not get fabricated in the initial effort, they serve to demonstrate the performance, bandwidth, and capability of this GaN process and could potentially be fabricated in the future.

Video Graphics Modules

WOLF Advanced Technology
Stouffville, Ontario, Canada

https://wolfadvancedtechnology.com

WOLF Advanced Technology (“WOLF”) recently announced that NASA has chosen two WOLF video graphics modules to take part in the development of NASA's X-59 Quiet SuperSonic Technology (QueSST) aircraft. Now under construction by Lockheed Martin Aeronautics Company at its famed Skunk Works plant in Palmdale, California, the X-59 is designed to reduce the noise generated by a sonic boom. Once fully tested and pronounced safe to fly within the National Airspace, the X-59 in late 2022 will begin making supersonic flights over select communities to measure residents’ reactions to any noise they might hear.

Lange Couplers

The construction and port orientation of the Lange Coupler from SemiGen (Londonderry, NH) makes it useful as both a power combiner and splitter for RF and microwave applications. It is a specific type of directional coupler, which allows passive coupling of a defined amount of electromagnetic power. The sweet spot for Lange Couplers has traditionally been UHF to Q-band; the limit becomes frequency. Substrate height and strip width are inversely related to frequency, increasing loss due to the reduced amount of metal available to act as a conductor.

Underwater Drone Technology

Finding ways to overcome physical limitations so that humans can dive deeper and stay underwater longer has been an ongoing quest. Back in the 15th century, Leonardo Da Vinci drew sketches of a submarine and a robot. Had he thought to combine the two concepts, he would have created a prototype of an unmanned underwater vehicle, or underwater drone. Instead, the world had to wait another five hundred years.
