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.

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.

Millimeter-Wave 5G Beamforming and Phased Array Basics

Experts and major industry bodies have spoken — 5G will arrive faster than many envisioned, and our industry is in the middle of an age of innovation that has not been seen for 25 years. Companies developing systems for millimeter-wave (mmWave) 5G networks are in front of regulating bodies, working to anticipate where the market will move and how to meet the needs of their customers.

Radar Echo Generator Application Note

Radar test systems are essential in research, development, production and maintenance of radar systems. Most radar tests are expensive to carry out in the field and have a complicated setup and operation. This application note presents a solution for testing the complete radar system by generating any kind of radar echo signals with arbitrary range, Doppler frequency and Radar Cross Section. The Radar Echo Generator makes it possible to perform real time tests on many applications including aerospace & defense and commercial radar systems.

Making Effective Use of Doherty Architecture

With the evolution of 5G technology, the need for antenna array systems is growing. This increases the demand for efficient power amplifier implementations to support high-density setups. Imagine you could get 60 % more output power, 50 % more bandwith and up to 20 % efficiency gain per amplifier in a MIMO antenna array setup? Would you spend time on rethinking your implementation plans?

Solving the Top 5 IoT Testing Challenges

Since each generation of IoT devices needs to be smaller, more robust, easier to configure and use less power than before, designers and engineers need to know the challenges involved. Download the whitepaper to learn how to navigate these.

Achieving First-Spin Success in LTCC Components with Advanced Material Simulation Models

Since the advent of Network Synthesis Theory at the turn of the last century, filter designers have been developing ever more sophisticated solutions to translate polynomial transfer functions into working, physical components.

Characterizing Active Phased Array Antennas

This application note aims to explain test procedures and give recommendations towards characterization of the relevant parameters for active phased array antennas and their passive subsystem, as often used in applications for Mobile Communication and RADAR.
