TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Linearity Of The JFET And MOSFET When In Saturation Over The Entire Cycle

  Performing RF amplification in a way that is simultaneously linear and efficient has been a challenge in power amplifier (PA) design. Single transistor PAs can either be operated in a linear, but inefficient, current source mode of operation or as efficient, but nonlinear, switches. These techniques use two FETs, but this paper demonstrates that linear amplification can be achieved at high power with an efficiency greater than 60%, using a single FET.

• Testing A 24-28GHz Power Amplifier Using The 5G New Radio Test Standard

  In this white paper, we will introduce some of the main challenges in test and measurement of a device at mmWave frequencies, with a 26 GHz pioneer band defined for the UK between 24.25 - 27.5 GHz.

• Voltage Standing Wave Ratio (VSWR) Explained

  Explore the evolution of VSWR from its humble beginnings in telegraph lines to its vital role in modern RF engineering, illuminating its practical applications and underlying principles.

• Certium VCS Test System For Aircraft Manufacturers

  New aircraft need to have their radiocommunication systems tested with compact voice communication systems like CERTIUM VCS. This is cost-effective, space-saving, and scalable thanks to its IP-based infrastructure.

• Accurate Test Fixture Characterization And De-Embedding

  This application note provides practical hints to accurately characterize and de-embed these lead-in and lead-out structures with R&S Vector Network Analyzers ZNA, ZNB, ZNBT and ZND.
