White Papers

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.

The low-earth orbit (LEO) satellite realm has spawned an entirely new class of devices requiring innovations in crystal oscillator products to meet performance and price benchmarks. Manufacturers of space-qualified crystal oscillators, like Q-Tech, have developed a range of devices (XO, TCXO, VCXO, and others) to provide optimized price and performance for each orbital application. This paper will delve into the subject with the objective of providing an informed understanding of the elements that go into device selection.

The family of ZNB vector network analyzers (VNA) from Rohde & Schwarz are the perfect instruments for analyzing RF amplifier small signal linear and non-linear performance. This application note presents information on how to configure and use the R&S® ZNB vector network analyzer to successfully make accurate and quick measurement of basic RF amplifier parameters.

This white paper evaluates traditional state of the art platings as well a new proprietary plating, SURO720, developed in partnership by HUBER+SUHNER and Rosenberger.

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.

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).

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.

Designing RF systems to operate with wideband modulated signals, like 5G and RADAR, or with a large number of circuits, like active antennas, is challenging. AMCAD Engineering introduces new behavioral models for power amplifiers that include low and high-frequency memory effects allowing robust and accurate DPD algorithm evaluation and validation.

This article will provide a top-level view of Wolfspeed's large-signal models for GaN power transistors and their application in an RF design. The article will include an overview of Wolfspeed's GaN on SiC devices, the associated large-signal models, and their advantages versus real-world devices during the development process. The piece will continue with an overview of a typical design procedure and a case study, then conclude with a discussion of the resources available to designers and how to get started.
