Ultra-Wideband (UWB) radio is defined as any RF technology utilizing a bandwidth of greater than ¼ the center frequency or a bandwidth greater than 500 MHz [1] [2]. While UWB has been a known technology since the end of the 19th century, restrictions on transmission to prevent interference with narrow-band, continuous wave signals have limited its applications to defense and relatively few specially licensed operators [1].

Higher thermal conductivity and breakdown voltage makes GaN MMICs a key ingredient in the most critical aerospace, military, and satellite designs. However, while GaN on SiC RF technology is achieving widespread adoption in military and aerospace systems, reliability is a crucial requirement along with performance and affordability.

"The latest SDR modules offer SoC solutions with integrated I/O, ARM processors and FPGAs. Combining these attributes with superior signal integrity, phase-coherent sampling and multi-channel transceivers a COTS SDR system is an ideal choice for a 5G development platform. This article will familiarize the user with SDR using a multi-purpose COTS platform to reduce the time to market."

Exploring the latest RTCA standards for nose mounted aircraft radome and how to meet them using a test method which is faster, more compact and more accurate than ever before. 

Understand the basics on C-IST use cases and applications, the related system architecture and get a deep drive into the LTE based V2X protocol stack for out-of-coverage communication and synchronization. Get an insight into the physical resources and their assignment as well as the medium access control layer (MAC).

With the proliferation of digital phased arrays in commercial and aerospace and defense applications, there are many engineers working on various aspects of the design who have limited phased array antenna familiarity.

Leonardo Microwave Power Solutions Department offers a complete set of high power microwave products developed and provided by the LEONARDO Electronics Division team based in Palermo (Italy) since 1956, for the production of high power vacuum electronic devices. In the 90s the product range was expanded with the introduction of chip and wire technology for microwave microelectronics hybrid integrated circuits, modules and sub-assemblies.

Global rollouts of 5G, and the expansion of the Internet of Things, creates significant new RF filtering challenges and Qorvo’s bulk acoustic wave (BAW) filters have advanced to solve them. They’ve evolved to support higher frequencies and increased bandwidth, utilize complex multi-filter modules, and mitigate the small form factor dilemma.

3GPP 1) defined the fifth generation (5G) cellular technology in Release 15 to meet ITU’s IMT-2020 2) performance requirements and to enable a variety of services associated with usage scenarios such as enhanced mobile broadband (eMBB), ultra-reliable low latency communications (URLLC) and massive machine type communications (mMTC).

This paper discusses gallium nitride as the preferred technology over gallium arsenide for facilitating power levels up to 10 watts and providing superior performance with simpler handling and assembly requirements. Topics include circuit design implications for these higher power levels, surface mount packaging for simplified design, performance examples and applications.
