Designing Microwave PCBs for Successful Manufacture — Getting it Right the First Time

In PCB manufacturing, not all the potential problems that can threaten the successful manufacture of a complex microwave circuit are necessarily captured in simulations. This paper looks at some common mistakes we see every day in the manufacturing process, and how to adjust your design to avoid those pitfalls.

All-Digital Antennas for mmWave Systems

In order to realize high performance mm-Wave communications, beamforming antenna systems will need to be smarter, faster, smaller, cost less, have lower latency, and be easier to integrate than current technologies. Much like with previous telecommunication systems, integrating important processing and signal conditioning functions will help to achieve cost-effective and compact mm-Wave beamforming antenna. However, for complex mm-Wave 5G and Tactical Communications, simply integrating sensitive RF and analog hardware is unlikely to be viable in the near-future. An All-Digital Antenna approach leveraging Antenna Processing Units (APUs)/ASICs could be more promising and further reduce the time-to-market for highly anticipated multi-data path mm-Wave 5G and Tactical Communication systems.

5G New Radio - Fundamentals, Procedures, Testing Aspects

The 5G New Radio online compendium from Rohde & Schwarz covers all the relevant details of 5G NR technology – the fundamentals and procedures in line with the 3GPP specification as well as key implementation aspects.

Analyze EMI Problems with the R&S®RTO/RTE

The R&S®RTO / R&S®RTE digital oscilloscope is a valuable tool for analyzing EMI problems in electronic designs. High input sensitivity, high dynamic range and a powerful FFT implementation are key features for capturing and analyzing unwanted emissions. Learn more in our paper.

Reliable and Flexible Simulation of Angle of Arrival (AoA)

Simulate Angle of Arrival (AoA) with a multichannel RF simulator for reliable test of radar warning receivers.

Pre-launch Testing of Satellite Payload Application Note

At every stage of production, starting from the component design and eventually leading up to the final integration and launching phase, uncountable amount of tests are performed in order to ensure intended performance in all mission-critical aspects. The industry-leading accuracy of Rohde & Schwarz equipment described in this paper raises test yield and is a further means to make payload test more cost effective and reliable. This application note addresses system- and manufacturing engineers by focusing on CCR/CATR and TVAC RF tests of components and functional modules as well as complete satellite communication payloads at prelaunch level.

Design and Production Challenges of Wire-Wrapped Ferrite RF Passives for Broadband Applications

The next generation of wireless and wired communications (S data & video) are reaching ever increasing frequencies and require much greater bandwidth than previous radio delivery systems. As the frequency and bandwidth requirements have risen from hundreds of megahertz to multiple gigahertz, the performance of passives also need to step up to these new performance demands. This article describes the challenges of developing higher frequency and bandwidth wire wrapped ferrite RF passives, as well as some of the ways MiniRF is addressing these challenges and manufacturing ferrites for the next generation of communications technology.

Implementing High Performance Filters In Millimeter Wave Applications

In this White Paper Knowles Precision Devices takes a closer look at some of the considerations to make when implementing filters for mmWave applications such as 5G NR radios in the 24, 26, 28 and 39GHz bands.

Four Strategies for Becoming Your Own, Best PCB Designer

"Printed Circuit Boards (PCBs) support the functionality of just about every working electronic device in use today. If you want to make something that does something, PCBs are likely a component of your product design. First in a series of white papers, PCB Design for Smarties will share our expertise on the subject, helping you move forward to your next project, confident there will be smooth sailing from design through manufacturing."

Designing for EMI Testing (Step-By-Step Guide): Improve your Time to Market with Oscilloscopes

Today, R&D engineers face challenging time-to-market goals. Extending the product development schedule and delaying the product launch can prove to be extremely costly in terms of opportunity cost and lost market share. Nearly 50 % of products fail EMC compliance the first time.
