Thermally Optimizing a High-Power PCB

August 11, 2022

Targeting higher performance and efficiency, the power stages of battery-powered applications must manage high currents while meeting strict power dissipation and size requirements. This white paper illustrates a thermally aware workflow used by STMicroelectronics to optimize an evaluation board deployed in battery-powered electronics that achieved maximum system performance in a short timeframe.

Improving R&S®FSWP Measurement Speed

August 11, 2022

The Rohde & Schwarz®FSWP is a modern, digital signal processing based, phase-noise test set that performs many tasks in parallel in an effort to improve measurements speed. However, several measurement settings drastically affect measurement speed. This paper will discuss these settings and provide suggestions on improving overall measurement speed.

Is your Signal Generator Agile Enough for your RADAR System testing?

August 11, 2022

When testing radars, it is often necessary to use a signal generator to test up/downconverter chains. Frequency switching speed is important when evaluating an agile system, or simply to minimize test time. This whitepaper will describe the challenges and a solution that provides low phase noise and fast switching speed.

RF System Design Accelerators: Hardware Development Tools to Speed Time-to-Market and Reduce Risk

July 13, 2022

RF and radio system development is becoming more complex at a time that technical support is becoming more diffused. Design Accelerator hardware development tools can speed design and development. This paper presents how Design Accelerators reduce design time, an analysis of how different types of accelerator boards serve different development needs (from designing waveforms or developing software, to proving concepts and prototyping), as well as an exploration of the different levels of integration available in accelerator boards.

Introduction to the Metrology of VNA Measurement

July 13, 2022

A VNA measures reflection coefficients of RF devices and systems. To be very meticulous, each measurement should be accompanied by an uncertainty with a specified statistical confidence interval. To understand the measurement uncertainty, or accuracy, it is important to understand the contributing factors, which are explored in this white paper.
